Hi, Fender, I just rechecked the filament wiring, it is wired to the schematic which was also how the original owner wired it, i.e., all pin 4 wired to the same wire and all the pin 5 wired together with pins 3 of the 6AV6 and 6C4 wired to pins 4 of the output tubes and pin 4 wired to pin 5 of the output tubes, just like the schematic. I just moved the ground of the power supply caps to a separate ground rather than the star ground, no difference except now the in-rush current is now about 4 amps rather than 1.5 amps from before, this damn amp gets more confusing every time I do something to it, thanks
