The year would be also 1962 (RCC supplement No. 58), in fact the two schematics
I posted may have been on the market at the same time. Many areas in Canada
at the time had no FM at all, so a cheaper AM-only chassis was a good selling
argument.
If I may add a few comments, I would say that this is a fairly good introductory
project to tube radio restoration: the radio part of this unit is as simple as it
gets while remaining useable for listening, and the amplifier should be reasonably
good (with negative feedback as it is), although you should not expect tremendous
bass from such small output transformers. The negative feedback is effected
by resistors R40 and R41.
If you have a working AM radio (a car radio would be best for this), do some
listening after sunset (or before sunrise), you should get a number of stations.
You may be right in assuming that the audio stages before the outputs are
somewhat different from the schematic, this will have to be confirmed. Note
that in the schematic, each 12AX7 is part of both channels, so if one
of these tubes is shot, no sound will come out.
I look forward to the under chassis pictures. Bye for now.
