As replacements for the large cans in both Fishers, I purchased Cornell-Dubilier and Panasonic "snap-in" electrolytics, not finding any other can-type electrolytics.

Both are 105 degrees C.
The other electrolytics being axial, have axial replacements on the way.
I tried Digi-Key but the first few values I punched in were not bringing up suitable replacements, so I stuck with Mouser.
Well, I have a half dozen or so more receivers that will need to be recapped, so perhaps I will spend more time on the next order.
LED festoon lamp replacements are also on the way for the dial scales of both, from eBay. I'll need to do some more research on LED replacements for the Stereo Beacon lamps in both. The 440-T uses a 47 lamp to illuminate the tuning meter. I will have to open the 4400 back up to see what it uses. Every bulb in the 440 is bad; most in the 4400 are still good but will be replaced with LEDs anyway, for longevity.
Oh, I am replacing the 1 uF coupling electrolytics with 1 uF metalized film caps. They are somewhat larger than the originals, but I thought they would be better long-term.
