Try looking in the trading post section of this forum. those are Nelson Pass outputs for his amp series. Also look under the Pass Amp section. Everybody there has those outputs my friend

I have some but they are my matched spares for my Adcom car amps. I can't free them up to spare out , sorry... Best of luck those are pretty much everywhere.

also have you used http://www.findchips.com/

These are likely the output transistors. There are likely many more in parallel. If you don't replace ALL of the ones that are in the parallel group, the amp will not be as reliable as it could be. Many times, when these amps fail, they take out the power supply. This time you were lucky (assuming the supply didn't fail). If mixed outputs cause it to fail again, the damage may be much more severe.

Thanks,The amp is all fixed just waiting on those to be complete and real got it from trades and i have got rid of alot of my other amps and fixed to it use for myself.It works now without the 3 but,i am just on my hunt for 3 but, really need 5 to be safe.If i could find someone or a place that has the sets i need that would be great!I just found all my sources i use to not have them or they want way to much for them or i would replace all of them for the outputs.I will keep searching just would like to get myself back up working,lol.Isn't that the way it goes,
