does anyone have a diagram of the transformer taps for this rca stereo power supply. it is by itself at one end and it just has 2 tubes and a power transformer. it seems one tap may be bad. i think it may be the red and green that feeds the 2- 200v 100uf caps in series, but dont know what voltage should be there. and there is a single tap thats not being used and maybe i could use that if i know what the voltage is supposed to be on the red and green wire. this power supply chassis is a rva274. all it seems to have is heater voltage for the 2 tubes but all the caps are dead, no voltage at the caps or the diodes. caps were changed diodes test good.
