I got a prs-d4000f, it had a shorted output transistor. So i removed the pair, problem is they seem to be unavailable.
is there a substitute, i already checked octopart.
Thanks in advance.

Found a supplier, overseas..takes two weeks but i can wait.
Anything i should check.......am getting rail voltage +/-32.5 and the +/-15 for the OP amps .
right now I have no output on any channel, but this a.m. seems to work a bit different than any other am I've worked on.....it's 4 ch, but it can be bridged for both channels to be mono or mono but stereo (which requires all outputs in order to bridge
..am assuming this is why i have no signal output.

Ice ic... You supplied me with the schematics, service manual. unless I found them online and forgot about them but I can post them on here so you can take a look at them.
I really hope I can get this am to work it's a nice little 4 channel amp and I could use it.

The IC isn't labeled with any usable numbers in the manual. It's ICC3 in the service manual. PacParts wants $33 plus shipping for it. I was hoping that it would have a generic number on the IC itself.
it does not have a generic number on it it does have a date code on it I know this because the other ice ICs had the same code stamp.
But would 1 defective IC effect all the other working channels?

Ok, well all the other output fets tested good. I'll see if i can order that ice ic from pacparts, if it's not a back order item....
