Speaking of which.

Prior to all that I checked the continuity on all the magnetics (that was in the very beginning) and all were good.
So today I briefly powered up the transformer without the rectifier tube, it was good, so I put in the 80, then I broke out a spare 20 speaker (so I do not have to set the cabinet on the bench), powered it up, and the local station came loud and clear.
Also touching the antenna produces good signal, which is one more evidence of the RF xfmrs being good.
Hum is absent.
Voltages on the 24A plates have nothing to do with 230/120/30V, but I think this is because I measure them with a DMM. I had the same very problem on my 1st 20. I do not bother checking around much as I know with this radio this will require me to use that old mammoth of a meter I have with 1kOhm/V. I know all resistors are right on the spot, all tubes are good, so why bother. Plus it sounds just fine.
It is a simple radio.

Oh...even the light bulb light-bulbed up.

Tomorrow I will give it an alignment.
