Those drakes if in spec is a great find.Here's a nice 2204 starter kit if anyone is interested...
It even comes with a few extra parts.

What are the potential causes of that, addons welcome:
Heater intermittent voltage drop - PT htr winding
Doubt the extra 12ax7 heater current as these had the same drakes for the 2205 which had 5 preamp tubes.
shorting OT if run hot into an attenuator.output Tube failing if never replaced and run at mid to lower bias weak output when hot.
These things can be a roll of the dice but you could also be lucky, who knows what other mods were made or if done improperly.
I think it would be cool to get one of these combo chassis and put a mirror faceplate on it in a head cab. So it reads backwards but right side up.

Rebuild underway.
Tested each part with the gizmo.
Made a quickie bending jig with some scrap wood.
Populating the board.
Went back and trimmed all the long legs after getting everything positioned.
Soldering everything in to keep it place.
Replaced all the pots, tube sockets, filter caps and fuse holders on the chassis.
Temp mounted the board so I can cut all the leads to length.
I think that's it for today.
