Glad you got it worked out!
Refurbished this same radio over 10 years ago so my recollection will be fuzzy. Those micamold caps could be silver mica types instead of leaky wax paper types. Remember replacing only 1 of those in the push-button section to get the oscillator slugs to home in to the correct frequency ranges. May have been cap 24. Not aware of a way to tell the difference w/o destroying the caps but any caps in a tuning section less than 10,000 pF are likely silver mica which generally are good.
Mine had an intermittent hum problem that came days later that drove me crazy. Came down to a heater-cathode short on the 1st RF tube. The tube failed nicely in the radio and tube tester when it was tapped. The oscillator tube was really weak and would take minutes of warm up and suddenly blast sound.
Would soon get boring if it always worked the first time!
