The horiz sync was weak and I just fixed that by swapping out one of those micas, but after watching it for a few minutes after that the power transformer finally crapped out. When looking for I replacement, I'm not entirely sure what's going on in this power supply, I understand how the 2 seperate rectifier tubes are working off the same coil, but what I don't understand is how this -2.5V source is working: is the center tap on this transformer actually slightly over to one side and not in the center at 0v?
But then if the center tap was off center I don't think the output voltage of the power supply could be made constant, as each time the AC changed direction the voltage going into the rectifier tubes would higher or lower, so then maybe the -2.5v just has to do with a voltage drop across that 10 ohm resistor and that center tap is right in the middle of the coil at 0v, although that doesn't seem like it should be possible to be both 0v and -2.5v, I'm still confused...
