Kekoa: I'll take them.... 
All: Here is where I stand on the Canadian 39 at present.
I removed the original guts from the paper 0.25 uF cap I found yesterday, restuffed it with a new 0.22 uF cap, and installed it in the radio.
Both electrolytic cans were opened up, the old guts removed, and new electrolytics installed. One of the two had a thick paper outer covering; this will be reinstalled, but I am not going to reattach/reglue the upper aluminum shell which was hidden under the thick paper housing. I did reassemble the other aluminum electrolytic can, using J-B Weld to hold the pieces together. That will have to cure overnight.
I also rewired both IF transformers. Both of these have threaded adjustment slugs, and the entire assembly of each transformer is held in place by two "keepers," if you will, each of which screws onto each of the two threaded slugs and is tightened against the aluminum housing of each IF transformer. I'll provide a photo or two of this tomorrow. Anyway, these dig into the aluminum, weakening it and making it prone to cracking/breaking at the point of contact. One of the transformer housings partially broke at one of the "keepers," so I went around all four joints with a little J-B Weld to strengthen the housings at these points. Again, photos tomorrow to illustrate what I am trying to explain. I have only seen these types of IF transformers in many 1938 Philcos; in some Mystery Control Philco chassis; and in the larger Tropic models.
