I recieved yet another one of theese amps in for reapir.

The power supply fets were shorted so i replaced them with IRF3205's .
Also replaced the 10 ohm gate resistors. The drivers are also new.

I unsoldered the red/black twisted wires from the board on 1 side .

When trying to power it up as soon as i add remote voltage it draws excessive current.

Any ideas what this might be?

I looked up the wrong data sheet for starters.

The 3526 is the one i needed and i have good square waves on pins 13,16

The following gate resistors have 1 side with bad waves

R62
R69
R71
R76
R83
R86
R92

The all have bad waves on 1 side of the nothing near a square wave.
