Hello everyone, I was replacing the original capacitors from my 1934 Stewart-Warner Tombstone Radio the other day and I noticed that the original Coupling Capacitors in the radio seemed to be of a better quality than the usual "waxies" you find in other radios from the same time period, as the ends of the capacitors in this radio were plugged with cardboard endplugs rather than the usual wax endplugs. Were there other types of capacitors in the 1930s besides the wax coated paper caps that you usually tended to see in radios from this time period and were they a better quality capacitor than the usual wax coated types, were these maybe oil caps of some sort? I haven't had a chance to test them to see if they were leaky or not but the physical condition of these caps is like brand new yet, nothing leaking out of the ends or anything, the only thing physically wrong with some of them is that the cardboard tubing has been darkened over the years due to being near some high wattage resistors that put out enough heat to discolor the cardboard tubes and also being near the 2A5 tubes that also get pretty hot, because they seem to be driving them to their limit voltage wise.
