a few years ago, i wrote a detailed article on how to revive a vacuum tube tabletop radio. a great many people have found it useful. i think the crowd here may find it useful as well. the article deals with the most commonly found tabletop radios of the 40's-50's.
going back that many years, darwin had much more influence on how things were designed. millions of radios from that era were built as "transformerless". this means there is NO transformer isolating you from the power line. it was not intended that you go poking around in the radio while its plugged in. this design was commonly called the All American 5 but did exist in 4-8 tube variations. these AA5 style radios can kill you if you don't know what you are doing and are extremely common in the secondhand market.
if you have some technical ability and understand the dangers of owning a product that was designed when responsibility was placed on the buyer and not so much the manufacturer, then you may find this article interesting. i have quite a few of these AA5 radios in my home that i have restored and use on a regular basis.
enjoy.
