Hi Rob,

The negative of filter cap 56 is wired correctly. I am getting a reading of -15 volts at the center tap, 54 & 56.
I have also checked all of the ohm resistances of the power transformer are all within the specs of the schematic. Is there something else? Could a bad ground someplace be causing this ( I have looked for a bad ground but see one)?
