I have 136k ohms between cathode (pin 3) and ground. Should be sufficient enough right? This was with the HO in or out of the socket.
I left the Ho tube out and took readings from the PS at the resistors Kirk mentioned. The voltages were higher with the tube out, I didn't take them with the tube in because I noticed that even when i left the set on for 30 seconds to take voltage measurements with the Ho tube in it got hot quickly
with the HO tube out i had -95vdc on pin5 and -99vdc on pin 3. OK, maybe the tube is bad? so i put in another 6BG6 and fire it up. Now I've got -84 on pin5 and -71 on pin3 and i can hear the oscillator singing again --but still no raster.
pin 10 of the CRT reads 270vdc. R103 is reading 300k in circuit, could be the reason for lack of G2 voltage. Good side of R103 is 420vdc, other side (pin 10 on CRT) is only reading 270VDC.
pin 2 of the CRT varies between -95vdc and 40vdc through the range of the brightness control.
