Hello everyone, a week ago I received from a friend of mine from church a 1952 Westinghouse Model H-378T5 radio and when I got it home and tested it out it powered on perfectly without hum or anything and it still had all of its original Westinghouse branded vacuum tubes that still work perfectly, and what I find rather unusual about this unit is that the chassis is Bakelite and not metal or PCB like some units from that time period were.

Anyways I took the chassis out of the cabinet to further investigate how the Bakelite Chassis was put together, and when I popped the bottom cover off I noticed that the unit was still using its original filter caps for the power supply which kind of surprised be because of the fact that most of the time original 1950s vintage multisection e-caps are usually duds by now but not so in this old Westie, anyways another unusal thing I noticed is that there was one of those old black Bakelite coated paper caps with the 5 color-coded stripes on the outside inside the unit and the capacitor had at some point in time "vented" as part of the Bakelite coating on the capacitor was broken off and the paper and electrolyte insulation was exposed which I thought was rather weird because the radio still worked perfectly even with the "blown" capacitor in the circuit.

My question is, how is it possible for this radio to work flawlessly even with a "vented" coupling cap in circuit? Also what is it about this radio's power supply filter caps is making them still perform flawlessly after over 60 years (40 of those years spent in storage) especially considering that I have another radio that's one year older than this Westinghouse and its already on its third set of filter caps?
