Bingo on the power resistors.

Funny thing, I replaced these two resistors a couple of months ago, because I accidently touched one and it crumbled.

They are R190 and R191 in the power supply. R191 I had to replace with two resistors in series, its possible one burnt out. I wasn't too sure of the wattage, but it overheated. At R190 I get around 370V. R191, I tested the voltage in the middle of the two resistors and got 0 volts.

Soooo I have lost my 240 volt B+. Which powers my audio and horizontal oscillator sections. The reason my vertical worked was becuase the 340 volt source was there.

Thank you for your help! . . . . But now I need to pull that damn chassis. The resitors are on top, but on the far corner behind the HV box. Will let you know of my progress.
