Default Re: Ultra Model 50 (1937) Restoration

It's coming along nicely OTF.

Attached are the voltages I measured, albeit with a non standard mains transformer and a U12 rectifier valve. I seem to remember changing some resistors with no effect on anything.

I found that the IF and RF alignments were quite easy to get correct compared with some 50s sets that I've worked on.

Keep us posted.
