I will have to replace the film caps in order to test the B+ voltage. Is it safe to assume that the film caps are not the culprit? Should I just leave them alone? I don't even know how to convert microfarads to nanofarads.. I guess just 1 into 1000. Not a huge deal. But I can't even find replacements for these caps anyway. The 615nf measurement freaks me out. I can find .56uf 400v film caps on digikey, but that's it. Somebody here is saying it 62000uf. There's no way. Should I just leave these alone? I'm suspicious of the nearby transistor that's supposed to handle B+.

Zeno: Every single electrolytic capacitor was just replaced, so it can't be that. Soldering is sound. 130v is indeed marked on the underside of the board. So I should test it while plugged in? Where should I attach ground, chassis? If it's too high then a component has no continuity, and if it's low then it's basically shorting, correct? Also... Which contact is the 130? I can't quite pinpoint it... I guess I can just move around with the meter, until I'm sure I've found it. It can't be THAT far off...

The problem with my measurements is, I can't find replacements that match what I'm reading. The only way to get accurate replacements is by purchasing the service manual, the way I see it. But the film caps are probably fine. I believe my issue is elsewhere...

Should I give some of these solder points a good reflow?
