So I bought an amp for cheap and opened it nothing burnt and smells new, looks great. But has irfp064n for the power supply. All are shorted legs 1-2 in circuit. No power, is this a problem elsewhere besides the PS fets. And can I use the huf75344 in power supply

It's likely that the driver transistors have failed. They're on the driver board.
I use the 064 when the rockford amps use the large transistors. The fairchild transistor should work as well.
The gate resistors sometimes fail as well.

So I changed the npn and pnp drivers for the PS, and now the amp draws 3.3amps of current and I shut it off. Failed output somewhere, none shorted. Any other ideas?
5v, 10us
Read the oscilloscope page of the site (page 73). Pay special attention to 'best initial settings'.

There 5v on both of those pins. And Perry if you touch b+ without remote it draws current immeadatly don't know if that releavent or not.
Do you know the designation of the outputs originally for this amp. I'm wondering if they are in the correct order originally.
If the center legs for the two outputs in each channel are directly connected, the P-channel output (leg 3) connects to the positive rail.
