Fuses usually don't blow without a reason, and the usual cause on solid
state amps is shorted output transistors. The output transistors are the
ones mounted on the big heatsink. If you aren't experienced in electronics
repair, I recommend taking it to someone who is, as someone else said these
can be a very tricky repair. Especially if the outputs blew as a result of
excessive DC bias, a tough problem even for an experienced tech to track
down.

My Sansui 7070 receiver broke a few years back and I have recently
started looking into repairing it. I purchased the schematics for this
system. The two fuses for the rectifier on the F-2625 power supply
board are both blown. I am worried about replacing them and powering
up the system with out knowing why they are blown in the first place.
I do not want to damage the system any further. Any ideas on how to
proceed?

Thank you in advance for your time.

Sincerely,

Marc
