50A made in canada missing a tube but in very nice shape i thought 100.00 plus shipping is very fair but the schematic i found isn't giving me much to go on for parts values.

Seems to be missing the 80 tube. It should be in front of the the big tube (47) in the picture.

thank you for diagrams and schematic Ron they are very thorough.
Is 100.00 fair considering the condition? The cabinet looks solid.
It's ok. A bit more than I would pay but within reason.
The grill cloth is made of curtain..... needs to change.
considering the same radio is worse shape is 300.00 in my local antique shop which i think is nuts.
Good point.
Otherwise I agree with Mike. Additionally, you have the Canadian version which is harder to find (especially here in the USA) than the USA version.
Any differences between the canadian version and the us version besides being 25-40 cycles.
" . . . being 25-40 cycles. "
I wonder how they were engineered differently for the different frequency, if at all.
The power transformer will have a bigger iron core than one for 60 cycles
"The power transformer will have a bigger iron core than one for 60 cycles "
Interesting. I'm learning. Thank you David.
"The lower the frequency the larger the cap to filter the hum."
Larger iron core and greater-value filter caps. Hmmmmm, . . . not hard to see why we went to a higher frequency in the US.
Thank you Terry.
Some military gear from the 50's and 60's is 120vac 400cy. Pt are dinky and useless... The point is that the core and windings on a pt need to be resonant at the frequency on the power that is being supplied to it. Else it just gets hot and angry.
