Edit Reason: re read orig post

I planned to use the Standard switch circuit and card. I think the standard is laid out chassis side down. i could drill out the Standard eyelet card and then flip it over. My pre chassis will be separate and upside down - above the PS/PA. lots of room and access to the circuit cards. I read the other thread re wiring two chassis and took notes.
The ToT PA is warmer sounding of the two?
I have drawn out the PS/PA layout and also the power supply + 6VDC regulator card and the bias divider/pot card so far. Somewhere here (on the forum) you mentioned a fine point or update for one of the galactic ground drawings in one of the books. i cannot seem to find that again. I'd like to reread and make note of that post.
I hope I am correctly following your layouts - power in opposite direction of signal, transformer orientation, etc.
I bought a 2x12 pine cab on ePay. It is now loaded with one Eminence EM12 driver. I could post a picture for reference. It is slightly bigger than your 2x12 dimensions in SPKR and has a port across the bottom like the TL806. I can block/tune the port. I just did not want to build a cab. It was 10x the price of a sheet of ply though.
The 6k6 opt is an old hifi UL. Masking tape said Bogen. Could be, is Z mount and weighs 6.5 lbs. 40-50W? I could save it for another amp. But I have done that for a very long time.
The TUT 6-34 active resonance circuit should be followed by a coupling cap, correct? 10x the cap it follows, like a MV mod? I wrote two 12AX7 tubes and meant two 12AX7 triodes = 1 tube, the version on the right side of the fig.
