I know of no other drivers that would be the same. You'll have to order them if you can't get them locally.

If no one else can help, start a new thread and I'll try to help. I won't reply in a thread for a different repair.

I don't understand the statement about powering the amp and the scope.

hi, im back, i replace the ir4426 with tc4426, and the optos 2601 with the 6n137, i have all voltages ok, but the output fets are not working.
i put a wire betwen rca shield and amp ground, not sound.
about 110volts on the outputfets, so the PS is working fine
what i should to check??

[ray9043]

i see in other post how to check the out pin in the preamp, i do this:
put a 100mhz signal with a player conected to the rca inputs,
turn on the amp relay engaged and checked is ok
check the volts in the gnd and out pins on the preamp

i have -0.47 volts on this pin, with and without signal, i know something is wrong, but i dont know who is or where start to check.

[ray9043]

i check the voltage witch dc, not ac¡
now i check with ac and i have 0.01 to 0.70 volts in ac, but i change the gain pot because the other person who want to repair the amp stole me this pot, so i change with a common pot of 20k, i solder only 2 pins, the pins who change the oms from 0 to about 20k, so its ok but this pot is 20k or other value???
