I admire your circuit drawing skills. Mostly I'm commenting to bump the enquiry. You ought to get more response in the TV section.

I don't understand all the semiconductor diodes at/near the front end but a TV expert would be better placed to comment. Similarly there's a semiconductor diode and half an EB91 feeding the audio output stage (maybe one for AGC and another for detection).

Can you connect it up stage by stage starting with the audio stage but taking care of all the heaters first?

I wish you good luck and hope someone else chips in.
