I've gone over your response and here's what I've found. Again, anyone looking over our shoulders please chime in if I missed or goofed anything:

1. and 2: OK

3. It almost looks as if there is a component underneath the two brown 'lytics? If so, what is it and where is it connected? Or am I just seeing a terminal of tube B?

3. The 130.5 tap on the choke (looks like a transformer but has only 2 wires) goes to pin 8 of the 25Z6 and should not: change it to pin 6 of the 6Q7.

4. A resistor should be added between the two + sides of the brown electrolytics. It can go between pin 6 of the 6Q7 and pin 8 (or pin 4) of the 25Z6. This is part of the high voltage filter on the set. You can use 1000 or 1200 ohms at 1 or 2 watts. I'd go with the 2 watt for cooler operation.

5. though 8: OK

I think once you go through 9, 10, and 11, we may be able to get a buzz through the speaker from touching the top cap of the 6Q7.
