Can't remember if you've replaced the waxies yet. If not, it's probably time to do at least a few of them. The annotated schematic I think I sent you lacks component numbers. I've attached the schematic I'm using here.
Around the line scan:
- The big 0.5uf boost cap from the LOPT to HT+. Use 470n 400V as a replacement. The new part will look ridiculously small.
- The 0.01uf from V12b anode to the LOP grid stopper resistor. They used a 500V part originally so I used 10n 630V but I can't see why a 400V part shouldn't be OK.
- The 0.003uf LOP screen grid decoupler. I used 3n3 400V. Value not critical so 4n7 or even 10n should be OK.
- The 0.1uf from the U191 anode to 0V. Use 100n 400V.
While you are at it you might as well replace "that" cap in the audio output. It will save V11 and the audio output tranny from any punishment they might be taking. It's 0.02uf so 22n 400V. 47n or even 100n won't hurt if you don't have 22n.
