Hey all, just bought myself a sweet Bogen receiver for 12 bucks from a thrift shop. The model is a TR100X, which is from the late 60's (I've seen an ad for it from 1967). It works, gets a great fm signal, but I'm not quite sure how to hook multiple speakers up to it. I've been able to hook one up and get sound out of it fine. I am not familiar with vintage receivers and I am afraid to screw things up by screwing and unscrewing the stereo wire contacts in an attempt to get sound out of it. If anyone is familiar with this model, any help with how to correctly hook speakers up to it would be greatly appreciated. I do not have a digital camera, otherwise I would take a picture of the back of it. Thanks!

It would help if we knew what sort of connectors you have for the speaker hookups and what they are labeled. My guess based on other Bogen gear of that vintage is that you have screw terminals, possibly with different terminals for different speaker impedances (4, 8, 16 etc.).

Minor trouble shooting help?

So my Pioneer SX-626 has been pumping my music loud and clear for a long time, but it may have finally kicked the bucket. I was listening to an LP today and all of a sudden the left speaker started blasting a lot of static. I figured my speakers were shot, but when I switched to aux it was fine, all of the other inputs (Phono 1, 2, FM AM) had really bad static on just one speaker. Any words of wisdom for me, or do I just have to replace it?

Might just be a dirty switch or pot. Is it better/worse if you move any of the switches/knobs around (even ones that don't seem relevant)? If so, a cleaner like Deoxit will definitely fix that problem.

I don't really have the facilities to do that. What would I need?

Edit: I've got this carbon fiber brush...

That brush plus some soap and water is really all you need. Wet the record, being careful not to get any water on the label. Get a little soapy water, dish soap works fine, and dip your record brush in it. Go over each side in a circular motion a few times. Rinse the record, let it dry, and that's all there is to it! There are definitely fancier solutions, and I have no doubt that they produce superior results, but I've had good luck cleaning records this way.

Note that you might also have physical wear on the records. Vinyl is somewhat soft, and if it was played with a very cheap or mis-aligned needle the record surface will have been worn down. Unfortunately there's nothing you can do to fix that.

I have an pioneer sx-770 blackface model and i currently have some cheap sony bookshelf speakers plugged into the A channel. My parents just moved and they found a no name subwoofer probably from some 5.1 surround sound dvd box set thing. I was wondering if I could plug the speaker wire into the B channel or would that be a bad idea.

Hard to say without more information. Some subwoofers are set up to take speaker-level inputs and some aren't. If the sub has inputs for bare wire, especially if they are labeled with the word "speaker" in some fashion, it's probably okay, but no guarantees. Is there any information on the sub at all? Can you take a picture of the inputs?

Probably no compression or other fuckery, the USB output should be directly converted to digital after the preamp and RIAA curve.

I just lucked into a very expensive record - I mean VERY expensive, like over $1000 - but I'm not sure how to proceed. I'd like to rip it before I sell it, and I have a reasonably high quality stereo setup (Pro-Ject Debut III w/Ortofon OM10 -> Harman/Kardon 3490 -> Edirol UA-5) but the record is fairly dirty and I'm really nervous about cleaning it. I've cleaned a ton of records before, and with good success, but using tap water and dish soap just seems too daunting in this case. Similarly risky things like the wood glue technique are right out. Should I start hunting for someone with a VPI machine or are there better high-quality methods? Obviously I don't mind spending a few dollars on this, but I'm not going to buy a record cleaning machine just for one LP.

It says it's a universal radio product made in Canada for the T. Eaton Co. Model No 1T85-E. I don't know anything about it. All the tubes are still in it and it doesn't have anything missing other than the one knob. The guy I got it from says it turns on and lights up but it's very quiet. I'd like to restore it. Anyone have any pointers?

Very cool! Anything that old is definitely going to need replacement capacitors. Check out http://antiqueradio.org/recap.htm

Thanks for the link. I'm almost afraid to start taking it apart. I think this thing is only worth maybe $100, but I don't want to ruin it.
I found the schematics for the radio so I hope I can find all of the parts to replace. I turned it on and 4 of the tubes started to glow and it made a hum from the speaker. It got pretty loud. The face doesn't light up.

2014-63 by Tom Rintjema, on Flickr

Edit: After I let it warm up a bit the face started to glow a faint green. I turned all the knobs and dials and almost tuned in someone talking. There was still a ton of static and an over powering hum.

Not at all a surprise about the hum, either your detector tubes or your preamp section aren't getting the correct voltage because your capacitors are shot, and the amplifier section is amplifying hum instead of amplifying signal.

I would only be worried about resale value if I was trying to flip this. If you get it working, the personal satisfaction value is going to be very high. Even if you don't decide to restore the electronics, if you can find a replacement knob and clean up the exterior, radios that size make wonderful decorative pieces.

Can you pull the "face light" out of the holder? It should just twist out, and part numbers will be very helpful for figuring out what a replacement might be. With that many wires running to it, it might actually be a tuning/reception indicator, something like a 6E5 or 6AF6 tube. But honestly, that would be the last part I would worry about restoring if you want to have this radio be functional.

The tube leading to the face reads 6G5 and has 5 wires going to it. One of them is heavier than the others.
I'm going to take the bottom off of the radio and have a look inside, as soon as I figure out how to hold it upside down without bending the front panel. Can I take the tubes out and wipe them off without hurting them?

You don't just have an AM radio, you have a shortwave radio! It looks like you've got coverage on some bands that are still used. The top one especially, ~6MHz, will probably pick up quite a few stations at night.

Usually the best way to work on the electronics is just to rotate it 90 degrees - lay it down on either the left or the right side, whichever seems more appropriate, and you'll probably then have easy access to the underside.

The 6G5 points to this being a little bit later radio, but that's definitely a tuning indicator. The face will be brighter or darker according to whether or not the radio believes that you have tuned a valid signal. Is it in a socket? Most of them were, but I suppose it's also possible that they were directly wired.

Be careful wiping down the tubes. The dust and dirt on them doesn't impact their performance at all (unless it's really bad, and it doesn't look like that's the case here), and unless they were run for a very long time they're probably still OK. Most tubes had white printing on them, and the fact that it was on glass makes the printing very easy to accidentally wipe off if you press too hard. Use a soft touch.

I had someone try to sell me a Macintosh receiver with a cracked faceplate recently and while the price was right, the damage caused me to wonder what else was wrong and I decided to pass. I suppose it didn't hurt that I was still able to get a bunch of other good pieces from him, including Ampex AG-500 and Akai X-5000W reel to reels.

Okay, I'm on the hunt again for a vintage stereo receiver and probably some vintage speakers to pair with it for setting up my turntable in our living room. Ideally I'm looking at refurbished 1970's Sansui, or Marantz, Pioneer, etc.

Budget is less than $200 but if I can find a bargain deal on craigslist and have it restored w/out paying an arm and a leg then that'd be good too. I'm willing to pay a bit of a premium for aesthetics but I don't need a top of the line quad receiver or something high-powered as it just needs to be loud enough to power some smaller speakers for our living room.

My priorities are:
1) sounds good
2) looks good

My questions are... can anybody tell me what the minimum wattage I should be looking for is? What are some good classic speakers I should be keeping an eye out for? Is there an easy explanation somewhere of model numbers for Marantz, Sansui, etc, so I know what to keep an eye out for?

Also looking for a good record player stand/console if anybody has seen any online.

If you can get lucky maybe you can find a Pioneer SX-780 or the like at a thrift shop? This is assuming that you live in a big city and have a number of thrift shops you can visit on a regular basis. A pair of Dynaco A-25s would be ideal for that sort of setup but again, at this point you'd have to be extremely lucky to find them at a good price.

If you're concerned about looks over functionality and you want high-class '70s style, keep an eye out for B&O stuff.

If you're concerned about sound quality over style but you still want the '70s look, get a Pioneer amp/receiver and keep an eye out for older Klipsch speakers.

Which turntable? We've obviously got some folks that really know a lot about this stuff here.

ED: 2 questions, all. First, where's a thread where I can brag about the latest vinyl I've scrounged? And secondly, about my needle. I buy a lot of pretty beat records at thrifts and whatnot and although I usually do a pretty good job cleaning them by hand, I still find the needle getting dust and dirt on it. I decided some time ago to use a small blast of air rather than a brush to clean the needle. Thoughts?

As far as cleaning your needle goes, most manufacturers of higher-end needles tend to recommend a soft fiber brush. Compressed air has the potential to knock the needle out of alignment, especially at full power, and I wouldn't recommend it. I've seen folks who are concerned about very dirty needles talk about using a magic eraser pad on the needle, extremely gently, but I'd still be worried about damage from that. At the least you are going to significantly shorten the life of the needle that way.

Most folks who play a lot of dirty/scratched records tend to have two different turntables, one for clean vinyl and one for dirty. That's the case at the shop where I work, and I've started to do that at home too. No sense damaging a $100+ needle with a lovely $3 record.

I recently inherited a pair of EPI 201s and they're big. And when I say they're big I don't mean, "oh, these make my large-ish bookshelf speakers seem small," I mean these things have some size on my Klipsch KG4s. Unfortunately I don't have any pictures right now because they're in storage, but the page of the guy who restores them is here: http://www.humanspeakers.com/e/epi201.htm

I got a brief chance to clean the worst of 30 years of dust off of them and test them (with a Lepai 2020, not nearly enough power) and they seem basically fine. I'm sure I'm going to replace the unnecessarily complicated crossovers; I suppose having the option for these to be 16 ohms was novel when you wanted to crank the hell out of your 20W amp but I have plenty of stable four ohm power to give them now.

I suppose my question is, how on earth am I going to deal with trying to get reasonable reproduction out of a speaker with an angled driver? For reference, with the grills off they look like this:

The front is flat, and the top is angled downward at maybe 30 degrees. The idea, according to the manufacturer's blurb from the web page linked earlier, is that you put them flush against a wall and they bounce sound all around your room. So great, I have to figure out how to deal with gigantic Bose 901 wannabes. I need some guidance here.

Options:
-gently caress it, dump 'em, who cares, it's not like these were nice speakers or anything. (They definitely were.)
-Disconnect top woofer and tweeter. This is not ideal, the top woofer would still work as a passive radiator.
-Wire top woofer and tweeter as a separate speaker so that they could be used separately for room EQ purposes? This would require a 4.0 setup in room EQ software, right?
-???
-Enjoy them as they were meant to be listened to (comedy option)

I went from a crappy belt-drive Thorens, to an SL-1500 (direct drive, no quartz), to an SL-1210 Mk 2, to a CEC DD-8200 (direct drive, no quartz) and now I'm deciding between the SL-QD33 (full auto, quartz) and a JVC QL-A2 (auto return, quartz). Aside from the Thorens, they were/are all great, no difference in sound quality when using the same cartridge and preamp.

You are considering a p-mount, why? Ease of setup? Nothing against the SL-QD33, I actually just fixed up and sold one the other day, but I would think after owning an SL-1210MK2 that would seem like a step down. I recently got an SL-1700MK2 and for what I expect from a turntable it's the best of all worlds. I can use a standard headshell so I can use a standard cartridge, setup is straightforward, it's quartz, it's auto-return but there's a button to turn it off in case I want to hear a runout groove, and just for giggles the cueing is motorized (I did have to replace the cueing belt, it was readily available on ebay and an easy install). Oh, and did I mention that even though it's direct drive it's a true floating suspension? They can be had for fairly reasonable prices because the DJs couldn't care less about them and they're way too auto for the hipster/DIY folks.

Oh, by the way, that old JVC JL-A15 is one of the better turntables we've come across.

I have no doubts it'd get whupped by a 1200, but I expect you could probably find one of these a lot cheaper.

You're seriously debating the merits of a turntable that was ~$100 new in 1978 (the Micro-Seki you mentioned) versus a JVC that couldn't have retailed for much more? Versus a 1200??? I would certainly hope you could find either of those for "a lot cheaper", I'd be ashamed to sell a restored one for more than $100.

Look, in all fairness I'm not here to poo poo on anyone enjoying a console stereo, but pretending those things are actually producing quality audio by any definition of the term is just silly. Even fully restored back to original condition you couldn't get better sound out of something like that than you could get out of hooking your phone up to a modern low-end guitar amp. The reason to enjoy a vintage console is as a fun piece of retro furniture, and any noises that it happens to produce are just a cherry on top.

I do have a tendency to overspend on things that I think are cool even when it's completely unnecessary so I appreciate a little reasonableness being encouraged. For reference I won't be ordering a driver until the rebuild on the power section is done and I can assess what's worth putting on the other end of it.

I think one of the more important things here might be to make sure you have a reasonable impedance match between your amp and whatever replacement driver you get. Are the original drivers 16 ohms, or 8, or something else? Older tube amps are much less forgiving about impedance mismatches than a modern amp.

Fane Sovereign 15-300 TC.

~$100, 50Hz - 15kHz, and if the impedance matches I'd say it's a reasonable replacement.

quote:

I would be fine with multiple drivers for this project but the layout of the cabinet makes things tricky as the original design had all the highs basically pointing at your shins, the coax driver idea at least got things to crotch level.

Okay, that makes more sense to me in terms of why you were looking at coaxial drivers. If you wanted to get creative you could make a shim in order to angle the driver upwards but that's not necessarily an easy task and you'd definitely want to make sure that everything was still sealed properly. On the other hand, are you primarily going to be listening to this standing up or sitting down? If the answer is the latter I wouldn't worry as much about trying to get the high frequencies up as high as possible.

Getting a coax driver obviously also removes any need for any sort of crossover network - if you were going to replace all of the existing drivers you'd either need to make sure they made sense with the existing crossover or build an entirely new one, and then we're getting into speaker design territory which is a deep rabbit hole.

I guess a capacitor has given up the ghost? I examined the innards, have the repair manuals, but am really suck at electronics.

The first step is to be sure that it really is the amp and not the speaker - switch the speakers and see if the problem persists. After that I would clean all the switches and pots with Deoxit. Only at that point would I start thinking about capacitor replacement.

Good lord dude, that's a really impressive speaker setup. So what Magnepans did you get that tore you away from Klipsch? I'm in what might be a similar situation, I have a pair of KG4s that I've loved for many years and treated really well - titanium diaphragms and a full re-cap - but I've been increasingly interested in Magnepans and having a pair of planar magnetic headphones that I really like has only increased my desire.

I found a pair of MG3a's for a song because they were water damaged, ended up making new frames from Baltic birch and replacing the old oak side trim with solid walnut since they had also warped. One thing about them though is that I re-glued some of the bass section wires to the membrane and it missed one tiny spot so I now have to take one of them apart again which is a pain as it is rattling. Any of the older aluminum wire models will eventually need this maintenance so if you're not handy or patient I wouldn't suggest it. It's not difficult work it's just finnicky.
For sound though, I can't speak to the smaller magnepans but the 5' ribbon in the mg3a's is just the most insane tweeter I have ever experienced, the best way I can describe it is that huge presence you normally get with bass but with treble. I would absolutely recommend any of the models with the true ribbon tweeter. They're very very "sweet spot" dependent though so if you don't like sitting down to listen to tunes in one spot, again, wouldn't recommend.

Also if you're curious, here's the build for the two way "klispch" speakers I put together.

I don't know what you're doing on SA. You're clearly a successful professional with an impressive amount of skill at a craft that demands precision and patience. The rest of us are anywhere in between "I found these lovely Panasonic speakers at the thrift store and overpaid for them, did I do a good job?" and "I've had this project half-finished for months and I don't trust myself enough to do it right even though I'm sure it would be fine," not to mention the "I make too much money and am willing to spend it on absolute garbage overpriced headphone DACs" crowd or whatever the fad of the moment is. Hell, I was proud of myself for successfully salvaging a botched soldering job on a pair of old KLH speakers that I was fully willing to throw out a window if I couldn't save them.

About the Magnepans, I understand that the high end is the attraction but can you speak to the low end? I wouldn't say that I'm particularly looking for "slam," and that's certainly not an issue for my headphones, but is the bass something that a normal listener would need to supplement with a subwoofer? My concern is that a subwoofer to match that caliber of speaker would cost almost as much as one of the speakers.

For the magnepans the low end was the surprise for me, with the mg3a's anyway since they have a fairly large panel and I could get them about 4 1/2 feet from the back wall they need zero subwoofer. I've measured them down to =6db at around 35Hz in room, they are a full range speaker that does everything well. I have bottomed them out maybe twice and that was with a Bryston 4B that puts 400W into a 4ohm load playing "hey now" by london grammar which dips in the the 28hz range about a minute in (great test track for stupid bass).

Wow. I use Chavez - The Guard Attacks as a test track for sub stuff; it has a sweep at the beginning down to ~31Hz and another one at the end, with a bonus little clip of ~22Hz at the very end. But really, you put 400W into your house/ears at some point? I have an HK 3490 that puts at least 150W into 4 ohms and it's way too loud at -20db. How big is your listening room?

Oh boy... saying "recommend me a pair of bookshelf speakers" is essentially a futile exercise unless you provide some specifics. By "bookshelf" do you mean 12" high or less? Are you going to run them on stands or on an actual bookshelf or somewhere else? Are you going to pair them with a sub? What is your budget? (I see you did actually answer this last one).

I have a pair of B&W DM302s on an actual bookshelf, paired with a Pioneer Elite sub and I like that combo but I can definitely say that it wouldn't work for everyone.

At my last job I had a pair of Polk Monitor 30s sitting on my desk, powered by a 20W class D amp which was obviously plenty for very nearfield listening in an environment where I wasn't ever going to crank the volume. That was fine too, though I'm not sure you can get those speakers new anymore?

I honestly wouldn't go more than ~20 years old unless you're looking for something very specific that you're already familiar with the sound of. Like all things, speaker technology progresses over time and there are definite tradeoffs when you're looking at older speakers.

A decade ago I built a 2.1-channel bedroom system around a $50 pair of white Realistic Minimus 7

I will honestly never understand people who have a soft spot for these speakers. They are boomy as all get out and don't take well to large amounts of power. I have a pair that I relegated to my bathroom for "I just want something to make noise while I am taking a shower" duty and even there I keep thinking about replacing them with something else. They were a reasonable option at the bottom end of the bookshelf speaker market 30 years ago but they've long since been eclipsed by... well, practically anything new at any price point.
