Thanks for your help! This chassis does have the 42 driver tube though there is no indication of the B model. I actually powered it up this evening (having changed all of the caps and resistors) and it came to life just fine (except that the output is low cuz of the transformer.) Now to get it lined up.
My older brother had this chassis by his workbench when he was a kid. I too used it back in the 60's. I may leave it just the way it is for the nostalgia of it all! It was fun to listen to the top 40 while watching the tubes glow in the dark. I know the transformer was out back then already as you could pull one of the output tubes with no effect, but the other would kill the sound. I ordered the universal replacement from Mouser this evening. They had one in stock. I hope it's close enough. At least it should be better than what I have now.
Interestingly, the shadow meter works backwards. Should the vane be straight with no power? Mine is bent to one side. If it were straight with no power I think it would register correctly. It doesn't move a lot though so the magnet may need a little help.
Thank you again for your help. I'm enjoying this phorum. I have another Philco to rebuild as well - a model 96. The help here will be great.
