Thanks. I will look at getting the anode voltage down, although it really shouldn't matter
too much.
Filament voltage yes. I've been reading a bit on the effects of under and over voltage on valve life expectancy. Seems thorium can be upset by anything that isn't in a data sheet.
As an aside, now the radio has power, it's looking like one of the trimming slugs in an I.F transformer has dropped off its screwed rod.
