I have the same 3 band set, unrestored and fully functional.  The electrolytic caps and selenium rectifier are original and functional. I do have to pull this one apart, and recap as I thought, based on a slightly newer one that since that one had ceramic disc caps that this one dod also. Now that I have seen your pix, I need to check this out further.

WARNING!!! These are true HOT Chassis sets, and, of course, are made more dangerous by the switch being on the chassis leg of the power line, creating a condition that depending on the plug polarity and switch open or closed will ALWAYS leave a condition one way or the other where the set could be unsafe on the bench or with knobs missing. For example, if the plug is oriented with the chassis at neutral potential with the switch closed the chassis is safe, but then with the switch open, the chassis becomes hot due to the tube heaters resistance which is much lower when the tubes are cold. With the plug reversed, the chassis is cold when the switch is open because the tube string is at neutral potential, but with the switch closed, the chassis is hot. I always rewire these sets so that neutral pin connects to the chassis and the switch is on the hot side.

Note that all AC-DC AM-FM radios I have worked on are "HOT" chassis (power line connects to chassis through the power switch) as opposed to "Warm" chassis (chassis connected to power through a cap or cap and resistor to limit current at line frequency but to allow conduction at radio frequencies).

One of the keys to how nice this set sounds is the 8" speaker.  It sounds almost as good as my RCA 1R91 Livingston, whose 250V and 6V6 SE output and rather large OPT gives that radio its characteristic sound.  That set is restored.

Edwin Armstrong Is responsible for many major inventions in radio, including the regenerative and super-regenerative detectors, licensed to Westinghouse and RCA, the Superheterodyne receiver, licensed to Westinghouse and RCA and several FM radio patents as well as patents in radar. However, patent wars arose between him, De Forest and GE engineers for the Regenerative patent and Frenchman Lucien Levy for the Superheterodyne patent cost Armstrong both emotionally and financially. There was constant struggle between him and David Sarnoff, who was not convinced that conversion or broadcast radio to FM was worth the obsolescence of all that transmitting and receiving equipment, so Armstrong licensed his FM system to GE and Zenith. RCA then developing a competing FM system (the Ratio Detector) and, along with some factual research from the FCC regarding propagation and their desire to use the existing FM band for TV, migrated the FM band from the original frequencies assigned to the Armstrong system to the current 88-108 MHz band. Armstrong suffered constant grief from these lawsuits. When his wife (Sernoff's secretary) had an affair, Armstrong could take no more emotional pain and grew sufficiently despondent to commit suicide in 1954
