I'm working on an SA-5560 with blown outputs in one channel and could use some eyes on my prospective subs for the outputs, drivers, and pre-drivers.
Outputs
2SC1116A >>> MJ21194G
2SA747A >>> MJ21193G
Drivers
2SD381A >>> KSC2073
2SB536A >>> KSA940
Pre-Driver
2SC1628 >>> KSC3503
Relevant part of the schematic:
