Yeah I should have thought of a broken solder joint, fits the symptoms perfectly. I opened it up and just remade all the joints to be sure rather than actually go about finding the issue, and used deoxit on the pot. Whichever it was (Probably the joint) it's fixed! Thanks.

I own a pair of BEOVOX MS 150's. I recapped their internal boards and reformed the surrounds a few years back, and have enjoyed good performance. However the past few months I've had a worsening issue with one speaker (I switched the outputs to make sure it was the speaker). The sound will...

That's the other scope I have as well! EDIT: Keep an eye on the rectifying diodes. They failed a few years back and I had to recap the unit.

Now adays it's mostly useful for a beautiful Stereo Oscilloscope display! No manual but I was able to fix a low-voltage power supply issue with a full re-cap. I'm still having an issue with overheating causing one channel to fade out, but I plan to solve that by tracking down the issue with...

Hello, I have an SL-5 of which the rubber mat is turning back into oil, since it has special holes for pins to check record size I was wondering if anyone here had a better solution than just getting a generic mat.

I managed to get my hands on a beautiful old Sony TV tuner that I am using for its side by side audio waveform display. However it was a "prosumer" unit and I can't find any manuals for it online. I know some people on here have massive binders of manuals of obscure equipment and I was...

I recently acquired a PS-F9 Flamingo, and am having difficulty with a speed issue. The speed (on both 33 and 45 rpm) flutters (not wow, flutter (yes i know wow and flutter are tape terms)) like a belt driven turntable that needs new belts. It is of course direct drive, but that's how I would...

Yeah, I'm seeing a variety of similar issues being traced to various transistors online. I'm hoping someone here has enough experince with this range of models to give me a starting point. No, I don't have speakers plugged in right now but if I try to turn it on only the right channel's power...

Any ideas or suggestions for troubleshooting?

I recently acquired a Yamaha CA-2000 (the Japanese version of the CA-2010), and got it setup at the center of my system running on a step-down power transformer to safely use it here in the United States. It was running beautifully for a few minutes of testing so I left it on while I went to...

I recently scored a Yamaha CA-2000 (the Japanese version of the CA-2010), and it works perfectly and is in excellent cosmetic condition. I am left with the choice of either replacing my Kenwood Eleven III with it, or selling it for a considerable profit. The opportunity cost of the upgrade...

Those Kennys are nice, oddly the tonearm(s) remind me of 90's Denons. But a little out of my price range for the value. My main reason for upgrading is the speed controls are getting annoying on the Kenwood (Even after cleaning both sets of control pots it'll have a jumpy speed after a few...

Ideally under $700, but if there was a top end model that will leave me set for life that I like the looks of I could go a bit over $1000.

I'm in the mood to upgrade from my Kenwood KD-5066, and have a short list of requirements: Wood Aesthetics Quartz Lock Auto Return (I prefer Full Auto, but this works) I found the PL-570 to satisfy these but current prices are out of control on eBay. Before I spend a few months waiting for a...

Being a good boy and reporting the solution in case someone googles this in 8 years. The issue was a trace between the 8.3v rail and the transistor supplying the 6v rail. It was corroded by the adhesive fixing a capacitor added during manufacturing to the back of the control board on the left...

I was able to do more exploratory testing. What I have so far is: All lights are out Capstan motor keeps turning when play is not selected (not normal for this unit) Rewind brake fails to release. Pinch rollers do not move into their full "play" position. All these functioned normally before...

Well I finally had time to open the unit up, and found that the capstan motor was turning as well (not meant to be when not playing on this unit). I turned my back for a minute or two and suddenly the motor had stopped and the lights were working fine. I reassembled the unit, and now a few days...

If you have a nearby photography store, you might be able to pick up some Kodak Photo-Flo. I make the working solution and add about 1 part alcohol for 9 parts Photo-Flo (working solution).

All the lights on my EL-7 have gone out at once, resetting the unit does not help and the bulbs look fine. Even the small ones like the dolby and record timer light won't come on. Any ideas for a common cause to lighting issues like this?

The mid range woofer on one of my MS 150's is giving a distorted, muddy sound. (Vague and Uninformative, but I'm not good at describing sound. I reformed the speakers a while back, and noticed the issue today but it is of course possible it took until now to notice it. I had heard something...

Hi, I recently started trying to reverse engineer a VMC-110c, a cable that terminated in a large multipin connector for the SL-2000, and two composite video leads for the PCM-F1. However, that cable was almost never kept with the unit and they are now unobtainable. Luckily the TT-2000 timer...

Well, more than a year later I was doing some late night googling and remembered this project. I googled "sony 26 pin" and found this website. It has a handy little pin out! I'll report back once I make any more progress! I managed to find some female connectors that should be equivalent to...

I put a 6.3V .1A bulb in my elcaset deck after the bulb burned out, and it was bright enough that I'm worried about long term damage. I did some more searching and found a bulb that matches the 6.3V .07A listed in the manual. (fuse bulbs of this size are no longer manufactured, they are thinner...

I have two sony tape decks (EL-7 and TC-K7II) and they have slimmer bulbs than the standard 1/4" bulbs. They appear to be exactly 11/64" or about 4.55mm in diameter.

I recently acquired a Muntz HW-1A 4 track deck, and want to hook it into my existing Hifi rig. To accomplish this I want to add a line out to the unit. Below is a schematic of the unit, would I be able to "tap in" the rca jacks to the input lead for the Volume pots?
