pot

Hi, I am restoring an old Proton P1100 preamplifier. It has a lot of issues but I am slowly getting it back to working condition. There seems to be an issue with the potmeter controlling the base, so I removed it and tried to clean it. While it got better it's still not working as intended...

I had purchased a MAC 1900 that cosmetically was very nice, but internally was an absolute disaster. Took on this project and I hope that some of the work I did might help others. First off, I replaced some of the key transistors (orange/yellow dot, flying saucers, etc.) and changed all the...

Hi all. I have an older Sony TA-AV521 with a noisy potentiometer. It is a sealed unit, but I soaked it in cleaner, as well as sprayed it several times. I ended up taking it completely apart because it would not give me any volume on one channel even after moving it back and forth etc. So, here...

Anyone have any experience tearing apart a marantz 2238b or similar volume pot for a thorough cleaning? I can’t get a dead spot out of the pot by simply using deoxit through the opening. I have the pot removed from the board and the back metal cover removed on the pot. But it looks like the...

Hi all, I just bought an old but brand new Tivoli 'Model One' radio (platinum series - yay!). I suspect this thing is near 20 years old. Stations come in and play clearly, but... while I'm still dialing in a station, the audio output can be quite scratchy/noisy. The volume knob works...

This week I was wrapping up an AU-717 overhaul and noticed the volume pot was noisy around the 9 o'clock region. My first attempt and fixing it was to turn off the amp and work the pot back and forth through the full range a couple dozen times. This didn't help so I knew I needed to do something...

Hi, I created an account after searching extensively and not being able to find any info specific to my situation. I have a beautiful pair of Pioneer HPM-60's. I'm almost certain they're all original. They're rated for 60W/120W MAX and they have the cloth surrounds... maybe someone can chime...

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...

Hi i recently bought a preamp from a pawn shop. It works and everything the only thing is that the gain knob had to be pushed sideways to allow signal through i wasn't sure if it was broken. I didn't think so since i could get audio by maneuvering the knob. So i decided to clean it with contact...

Hi, I have been fine-tuning my very nice mc2255 amp. I have found that the gain on one channel is slightly higher (6%) than the other channel with both gain knobs set to max. I have cleaned both pots, but no change. I was thinking of adding a small resistor in series to the louder channel, but...

is it possible to completely remove power switch mounted on the back of the treble pot assembly on an Eico HF-81? how do I do it please?... do I have to remove (and unsolder) the assembly first to gain access to it, or can I do it with the pot assembly in place? the reason I'm asking is that...

Hey guys, So I just finished a 1200b and noticed that I still have audio out of both channels when the volume is at zero. At first i figured a bad pot but out of curiosity I plugged in a 1200 I'm getting ready to start and it has the same problem. Even when the gain switch is on low I have audio...

Howdy, I have a SA-5270 Technics that has a iffy volume pot *Or so I think* The Volume knob works and does the job of turning up the volume but it sounds like it doesn't send juice to the left speaker channel. If I push on the knob real hard it has full volume with both speakers. Once I...
