Latest diagnostic info........Disconnected one leg of the secondary AC side
of the transformer going to center junction of the 8 caps in the doubler.
Tried it again, and the plate meter still moved and the grid meter went
negative, however it took more ac mains voltage to produce a significant
the meter. Next I disconnected the other AC lead going to the diodes so
that the secondary of the transformer was totally out of the circuit.....now
meter does not move at all with full main voltage. Looks like there is
leakage on the power transformer to ground, I took a measurement across the
meter as it was moving and its only millivolts, but enough to cause the
problem. Suffice to say the power transformer is leaking. Guess we'll need
another transformer. This amp is one of the first made so the thing is pretty
old. Time to lay to rest. Lou
