[QUOTE=Electronic M;3207025]Good to hear you're making progress.

Definitely check your B+, h out screen and grid voltages, and report back...

Here are my results for measuring the B+ supply

Secondary winding ohmd out correctly at 7.3 ohms, 350VAC about 20v high.

Now the rest is just totally off.

B+ 1 455v

2 454v

3 436v

4 375v

5 372v.

6 288v

Its all jacked up. On pins 1-7 for the hor output grid theres 432v even though theres two resistors between the screen and B+ supply where its suppose to drop to 140v ! Pin 8 calls for -55v and its 27 volts positive. Dont get me started on how wrong the crt voltages are too.

I know bad E caps will cause low B+ but what about this?
