I got it all recapped. Still getting that additional 60 volts in the sound IF B+. Near 320 volts when it should be 260. Havent checked the video IF plate voltages yet to see if they are cranked up yet.

I get about 285 volts on V10 when the focus control is up near 1K and 320 volts when the pot is 0 ohms. Focus is sharper when the control is near 0.

No signal passing through anything of course since the voltages are so far off.

Resistance checks tomorrow.

Any ideas on anything specific to check?
