Question about fixing a stuck volume knob on an old stereo receiver
So I found a 1987 Kenwood receiver at a thrift store for $15 and the volume knob was totally seized. I had to pick between spraying contact cleaner in there or just yanking the knob off with pliers. I went with the contact cleaner first, sprayed it down the shaft and worked it back and forth for about 10 minutes. It loosened up okay but now the volume jumps around when I turn it fast. Has anyone else had this issue after cleaning a pot on an old receiver, or did I just make it worse?

Did you check if the knob itself is cracked or loose on the shaft?

Oh man, I read somewhere that loose knobs on older stoves are actually pretty common and usually just need a small screwdriver to tighten. If the plastic is cracked though you're probably looking at a replacement because the cheap stuff they use these days just gives up after a few years. Might be worth checking if the shaft itself is stripped too because I saw a forum post where someone spent hours on the knob only to find the real issue was the metal part underneath.
