Hello,
I have installed the completely stuffed board from Hoppe's Brain into one of three GFA-565 that I am working on. It has no bias at all, it has sound and no offset. Noticed that R-502 runs pretty hot with 15volts AC drop across it (no DC, which I think is weird since there is a diode in series with the resistor/transformer ). Can someone explain how the bias delay circuit works and what the voltages should be? I was thinking of swapping one of the other soft start boards to see if it changes the condition. The manual just barey mentions the soft start board.
Just noticed that the circuit around R-502 is floating in respect to ground, so the dc thing makes sense.
