The mica save was inspired/encouraged by this gem I found:

I'd wondered if it could be done, and for this style of transformer, it is possible if you are careful and have the nerve for it!

My minor dilemma now is that there are 5 more IF cans. Although there are no signs of trouble, the OCD side of me says they should all be checked. The leave well-alone side of me fears causing a problem...

Meanwhile, I found a suitable replacement for the 4 section electrolytic which should arrive in a few days. A slightly expensive approach, but as this radio is going back out "into the wild" it is the best option. I found one with 200 V ratings (50V on the fourth section), so a nice extra safety margin where it is needed. The diameter is the same, and although it's about 0.5" taller, this will not present a problem
