Working on a Pioneer amp and it looks like I have a set of outputs gone.They dont look shorted but the bias voltages are off and the amp shuts down.
Does anyone have a source for these they seem kinda rare.

These are likely obsolete by now. Are they those multilegged darlington transistors ?

 

[latala]

look towards Sanken they make these devices with interanal temperature compensation

Yes they are the 5 leg darlingtons. I can find sap15's, maybe I could move the 15's to the center channel and the 17's to the main channel... which is blown.

Anyone know if the SAP15 will sub the SAP17?

You can get SAP16's from http://www.profusionplc.com/pro/gex/psrchrslts .
Never heard about the '17-s.

you can get SAP17N & SAP17P darlington audio output transistors from:

Category - SAA - STRZ

are you sure you have no DC bias driving the bases?
