Fisher 800c right channel buzz

Larry -- I believe that the 220 ohm heater winding balancing resistors on the 500C/800C receivers are located over in the power supply area. Therefore, unlike the 400 receiver, the heater balance wiring "error" when installing 10 ohm cathode resistors can't happen on the bigger receivers like it can on the 400.

Dave; your right. I'm seeing output ghosts.

Dan. The resistors are R-101 and 106. They are on the end of the heater circuit for V9 thru V15 , the dial lamps and mpx heaters. And they are in the power supply area.

I've finished!


Aside from mounting the bias adjust board....

Buzz is gone, sounds clean.

Of note, I feel like I've lost a significant punch. There is no bass. I have to crank bass and loudness to make it sound any good. Maybe another thread....
