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
