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
