The Black Cats have all been replaced
I am Jumping over the Square Caps
and the .05 and the .1uf 600v Caps in the vert osc deflection circuit
the HV circuit has been reworked from one end to the other
I have changed 5 of the HV caps
The HV seems to be there
the problem seems to be in vert deflection circuit
The way i see this is the waveform comes from the tube plate coupled through the HV caps and kicked up to 6000v to the plates in the CRT
the HV side is good IM sure of it
also H DEFLECTION works perfectly
lots of gain!!
IM looking at the low plate voltages on the V OUT 6SL7 tube
the schematic shows 420V and 350 V I show 250 and 185
Yet the volts from the HV section is well over 600V on the volatge divider(the 2 6,8M ) resitors so the power is there the tube is not using it ??????
