Originally, I figured I'd restore this set a section at a time and see steady improvement. The reality though is that the longer I run it on those old parts the more problems pop up. Lost sound, lost vertical sync & height, etc.
Even one of the tubes that tested great developed shorts. Also, I tested about a dozen paper and electrolytic caps and all are leaky to varying degrees.
So, I think I'll stick with my usual approach of shotgunning all the caps right away.
Recapped power supply/amp chassis.
I'm about 75% done with the main chassis too.
Sync is pretty solid now but the sound is weak and the picture isn't as bright as I'd expect.
Also, the picture is too wide considering this set has a rectangular rather than "double D" mask.
Perhaps both those issues are related to low HV so I decide to poke around in the HV cage. Very easy to do on these sets. Just remove three screws and the side comes off.
There I discovered the 1M resistor inline with the second anode as about 70% high!
