Philco Canada 39 or 41-722 Tropic
#2

I started on this project yesterday, and here's the progress as of mid-morning today:

In this case, the paper caps you see are the new capacitors. Icon_smile

I'm going by the 41-722 service info because the Canadian diagram is much harder to read, plus it has no under-chassis drawing. I have found that the circuitry agrees with the 41-722 save for the power supply as mentioned in my first post in this thread.

There is a 5 pF mica cap, part (16A) on the 41-722 schematic. One lead of this mica cap broke off short as I was replacing resistor (7), so it will require replacement.

I'll also have to come up with a speaker connector - the original (the part that plugs into the back of the speaker) is missing. Unlike most 1939-1942 Philcos which use four terminals, this one uses three; much like a mid-30s RCA. I do not know if an RCA 3-pin connector would be an exact fit or not as I do not own any of those sets.
