Two 5A fuses on the CT transformer secondaries blown. This unit. has outputs for two rear speakers (L/R), a center channel (DIN connector) and two front satellites (L/R). Now the inputs are analog RCA audio so this. box must be just …

The original C2837/A1186 output pairs are LAPT type (Sanken's unique multiple discrete transistors on the die) which results in the best linearity from audio transistors that you can buy. The replacements are standard, triple diffused audio types like other manufacturers. Good and cheaper but not the same high quality device.

A lot depends on the reason the transistor blew in the first place. Very few fail for no reason. It could be the amp was driven too hard into too low an ohm speaker. However when a transistor blows it can often take out the drivers too so simply replacing the output transistor results in another meltdown.

In the case of the output transistors, if you find only 1 shorted in a group of parallel-connected transistors, you can reinstall the ones that are not shorted to see if the amp will power up. If it does, you need to replace all in that group of parallel transistors. This is generally only viable for audio output transistors. Generally, when one power supply FET shorts, all will fail and all will …
