OK. Some of it from the 6K7 rear, on to the front end is hard to follow, so I'll have more questions. If you could take pix at different vertical angles of the underchassis including the 6K7's and the 6A8, I could see where some of the wires go better.
What's the voltage at pin 6 of the 6Q7, if I didn't ask that before?
By the way, your red/blue/green transformer I.D. method worked great.
