The Fisher 500C Receiver With Channel Issue

[@geedaddy45]

Great video! I’m in the process of renovating my 800C as we speak. When I bought my 800C in Oct ‘22, the left side OPT was fried. It has been replaced already. Do you have an update video on the 500C OPT repair?

Hi, Great Video. I just bought a 500C yesterday to go along with my 500B I've had for decades. I brought it up over about 6 hr on a variac. Turns out the right channel is bad too. But it's not completely dead, there is some sound coming though at low levels but the vol control has no effect on it. Left is perfect. I swapped all tubes around and it's still the rt ch bad. I did check all the tubes on my BK and they checked good. But who ever had it before me was using 6L6's in it, and I understand the bias should be more negative than for the 7591's. Not sure if it was set up to use 6L6's. I will take the bottom off, look for anything that may be bad. Then follow what you did on the video. Since I'm getting some sound I wonder if it could be a bad quad cap maybe.

I wouldn't mind owning one either. Even with only one channel working it sounds nice, with both functioning it will really come to life and rock the house 😉
