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.

Scroll down and click on the Model 50 schematic. This one gives the parts values.
Or if you also want an under-chassis view and a parts list:

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.
RE: Bought my first cathedral. - jake wells - 06-01-2019
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.
RE: Bought my first cathedral. - jake wells - 06-01-2019
considering the same radio is worse shape is 300.00 in my local antique shop which i think is nuts.
RE: Bought my first cathedral. - Ron Ramirez - 06-01-2019
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.
RE: Bought my first cathedral. - jake wells - 06-01-2019
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.

When looking at the schematic the filter caps are different values for the 25cy vs the 60cy version. The lower the frequency the larger the cap to filter the hum.

"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.
