So today I put this panel in, screwed it down.
Forgot to solder it in.
Turned over, powered. Zero volts. Took me about 4 minutes to come to my senses. ;)
Luckily, no shorts (power wires were hanging inside) or otherwise bad things.
So I soldered everything.
Good thing about this radio, the B+ is loaded by a resistive load from the start so the caps do not experience large voltage rises before the tubes warm up, so I could safely use 400V caps where otherwise I'd use 500V.
The speaker is in pristine condition.
I pulled it out, plugged in. Powered.
The radio produced typical noises, hum dependent on tuning, some howling and a distorted weak station, all with no antenna.
The "local" mode where the Line is used for an antenna did not help.
I disconnected the antenna from Local, touched it with my finger and was able to receive my local station. It is not yoo loud and it is at full volume.
I suspect the radio is badly misaligned, plus needs neutralizing.
But.... it's a good result.
