Reliable Panasonic PV-4760 VCR now blowing fuses

[vintage]

My usually reliable Panasonic PV-4760 VCR didn't turn on the other day. Lifted the cover and noted the 125V 1.6A fuse in the power supply unit had blown. I replaced the fuse twice more but each one blew as soon as the unit was plugged back in. Any ideas on the problem? I would hate to have to trash what has been an outstanding component. Its vintage but it complements all my other high tech electronics and I'd like to salvage it. Thanks.

I would suspect either the mosfet or one of the rectifiers in the power supply has failed short circuit. If you're looking at them, also check for dead electrolytic capacitors.
