I am looking for schematics for an International Radio Corp.(Kadette) model 649 chairside. I can't find it listed in the online Riders.

Hi,
What is the tube layout? A similar one might be found that way.

The tube layout is 80 (rect), 41 (out), 75 (2nd det), 76 (ocs), 6D6 (1st det), 6D6 (IF). It seems similar to the Kadette 634, 635, and 3734. I am concerned that I have a bad power transformer. Filaments don't light up. I guess I should take AC measurements, but without a schematic I am not sure what to read (obviously I can check filament voltages, but since they don't light, I assume there is no voltage there, I know the tubes are good.). It could be an open primary winding, which would be bad indeed since it is not really THAT nice a radio to invest in a new transformer or re-winding the old one.
I have not done anything in terms or replacing caps. Could open/shorted caps or resistors lead to no filament voltage despite a good power transformer?
