why is it so hard to repair these boards?
i've rebuilt the entire board as it had been attempted by someone else,
but amp still going into protect with -70v on speaker output
take the driver board out and all voltages present and correct

Find the output transistors that have more than about 2v G-S. Which pin on this board drives those gates?
If you touch a load across the speaker terminals, does the amp draw excessive current or does the DC simply drop to 0v?
