If the main filter is not the hum check the outputs next
& any transistors direct coupled to them. They will probably get HOT fast.
Its probably the transistors mounted on the chassis in round
holders.

According to a thread on AudioKarma where a guy had a unit that had the same exact issue as mine (where it hummed and no audio minus the blown fuse issue because mine hasn't blown its fuse yet surprisingly enough) they said something about the amplifier's coupling caps being bad which then in turn caused the output transistors to become fried like bacon, and once he replaced the coupling caps on the amplifier board and replaced the output transistors it worked fine for him. I'm hoping that's not what happened with mine because the amplifier board is going to be darn near impossible to remove because for some reason or another the amplifier board's mounting screws are covered in solder so there's no way to unscrew them...
Well I guess I can forget about working on the tuner board specifically on the vernier tuner mechanism because the screws wont budge and the heads keep wanting to strip out on me whenever I try to remove them, which tells me they used poor quality aluminum screws for that part for some reason, which is odd because the rest of the screws they used were stainless steel screws...
