I just restored a late 40s Admiral model 7T10 typical All-American Five radio for someone. I figured it would be easy since it had the larger tubes and IF cans, and would not have the silver mica disease like many AA5s with the 3/4" square cans have with the caps built into the base of the IF cans. Wrong! This radio had larger IF cans that were slug-tuned, and after recapping it, found that it exhibited the symptoms of SMD- some erratic static in the reception, and increasing/decreasing sensitivity. These cans had caps built into the base but in a different way than the smaller type cans. Disconnecting the coil leads to the terminal posts and placing a cap meter across the caps revealed the values to be about 80pF, and modern 82pF mica capacitors worked great and the alignment was nearly dead-on. (This info might be helpful for any of you that might work on this model).
An interesting thing about this radio is that it might have been made with either these type of IF cans, or the older type that do not get SMD- the type with screw-adjusted trimmers on top instead of adjustable slugs and fixed caps. The schematic shows slug-tuned cans, but the tube placement/alignment adjustment diagram shows screw trimmer tuned cans. There is also a note that says that one of the adjustments for each IF transformer MAY be under the chassis (implying that both are usually on top). Interesting.
