You may want to post under Electronic Restoration. The Canadian Philcos sometimes use a different model and chassis. Try looking in the Gallery for a set that looks like yours and try that model.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!

It may be the Canadian equivalent to the U.S. later model 40-195 or 40-201? Check them out in the gallery.
Good Luck, John

John hit the nail on the head. I have a Canadian Philco 1940 year book...your Model 21 is a 1940 model, not 1939. (It would have been introduced in June 1939 as a 1940 model.)
Looking at the schematic, I see that Canadian Model 21 is electronically equivalent to USA Model 40-195.
39-6445E is not a valid model number in the USA or Canada. That is a part number for a sticker, probably the tube layout sticker.
The hum is probably caused by faulty electrolytic capacitors. You'll have to replace all of the paper and electrolytic capacitors for safety and reliability.
You will have to check and see if the wiring under the chassis is insulated with rubber or not. Philcos made in the USA between 1939 and 1942 used rubber insulation on the wires, and that stuff dries out and falls off over time. Yours may use cloth insulation? I have a Canadian 39-330AT, and its wiring under the chassis is mostly cloth, not rubber. The only rubber insulation it had were the wires coming out of the IF transformers.

Hello All,
Thanks to all for your quick and concise responses.
Yes, it is the Canandian version of 40-195, with mostly coth covered wiring. I will continue to post on the Electronic Restoration forum, as suggested soon.
Best wishes for the New Year.

Mostly cloth covered wiring? We should be collecting Canadian Philcos down here, then. You're lucky...you haven't lived until you have had to replace all of the rubber insulation in a set like a 40-195. Or better yet, a jam-packed chassis like a 41-226 "Sled."

Hi Ron,
If you are interested I can post the rear shot pic with wiring, with permission, as I 'm not familiar with another way to post the pic onto another server. Your call.
Look forward to learning more about this unit and what is involved in getting it to run properly.
