pots

I’m trying to find a new, currently-produced replacement for the tone pots on a 2225 PE-01 tone board. I suspect they’re the same pots used on multiple receiver models. 2-gang 100K linear pots with 11 detent positions. After much searching, I’ve found no drop-in replacement, and no...

Good Morning all. New to the forum and have a question. My Mother In Law works at a local “Goodwill” type place. She just brought me an STA-46 that showed up today. I wasn’t expecting much; plugged it in and hooked it up to my speakers. My Goodness! I was blown away by this thing. When I would...

Scratchy, Non-Uniform Old Volume Control We just restored a Fisher 800 (TA-800) receiver. One remaining problem: the volume control exhibits areas of scratchiness and non-linearity. I am aware that there is a spray product called “DEOXIT”, mentioned in these forums. However, I also read a...

After reading threads from in my case audioKarma member Kale, being amazed about how far he takes the restoration process and recently by Bumpalump I decided I will have to learn this side of the game too. Because I can not just go taking apart mostly unreplaceable potentiometers and switches I...

Hi all, About three weeks ago I got a pair of Infinity 5000 speakers, and after setting them up and playing around with the Midrange and Tweeter levels I discovered that they were very noisy when moving and sometimes the speakers cut off when moving the pots, last night I decided to finally...

Hello, I recently acquired a KR-8010 but I was having issues with the speaker channels outputting very inconsistently. I did a lot of browsing and I found this forum and some old threads of people with similar issues, primarily this one...

I’m trying to repair my “old” Yamaha the pots are very scratchy and would like to replace but I don’t understand the difference between audio , linear taper or much of anything else the pots are as follows, 340a 30kmn, 343n 20k x2, 340a s-16 x2 Thanks in advance

Please forgive this question as I've never had speakers with pots on them. In this case I have a matched set of EV Aristocrat III (i think). The brilliance and presence pots are...noisy. If you can get them tuned to a spot where they are not as noisy (crackles and fuzz), I notice that the mids...

I got these for free. Had not had a chance to check them out thoroughly with my restored Pioneer SX-1250. Due to working from home, I now wanted to ask for advice. These are three way speakers, with a dome tweeter (think it’s metal), a mid-range, and a large woofer. I felt the high end just...

Thanks in advance for any help. I have a pair of cherry just purchased from the original owner Sansui SP2000. After doing a lot of reading and research on here I ordered all new capacitors. I didn’t go crazy but I also didn’t order the cheapest. But there are no spades, everything is soldered...

Hi, I just received an old mixer from the eighties that has been stored away in a basement for more than 20 years. It was stored in a flight case and all the pots and faders are "glued" and wont move at all. Of corse I dont use much strength to try to move them since that would totally damage...

Hello audiokarma, First post here. I'm in the process of restoring a Sansui QRX-7001 that I inherited from my late father earlier this year. I didn't even know how to solder when I began in June - by now I've completed two DIY amplifiers and a preamp and have recapped and replaced (some of)...

So I replaced a very hard to find balance control on my 2285B and decide to explore the old one. It didnt work well, the right side would cut out and all kinds of noise when turned even after DeOxit, cleaner and Shield. What I found was you could see the ohms resistance jump around when you...

The popular opinion is to soak the heck out of the pot with DeOxit, swish the control many times side to side, then rinse to wash out the "gunk". And to be fair, that does seem to work pretty well. I now use a method told to me using the needle version of DeOxit and a more targeted way. The...

So when I bought my 2285B, I didn't know it was such a rare beast. I got it done but I had a poor condition balance pot and a volume pot that had a bent shaft. Both are unique to the 2285B and the balance pot has a detent click in the middle. What I found after a significant amount of digging...

I have a Marantz 2240B and it has been working great for a long time. I decided to replace all factory lamps with LEDs, this includes the tube lamps and indicator lights, including the Stereo light. After replacing them, everything was working great for about two months. Now as I am listening...

R765 trimmer behaving unreasonably while being adjusted did quite some damage on my right P750. I intend to replace all pots now. Not at all sure about the power rating though, in the specifications are all marked as "B". Any advice please? This series available at Digikey seems to be...

Hi everyone! I recently acquired a Pioneer sx 1010 receiver, and am super excited about it! It has the common scratchy, intermittent pot issues. I have successfully cleaned my Kenwood KR 5400 pots with deoxit. Does anyone have any thoughts or suggestions about the 1010? Is it reasonable for a...
