Now there's a blanket statement if I ever heard one. My experience with the tube era was that a power supply would commonly have problems with either the rectifier tube or the electrolytics. Back then - as a teen, that is - I was a lot better at replacing tubes and swapping out electrolytics than I was at anything else, so take this with a grain of salt, but there did seem to be a lot of tube failures. The tubes that ran hot in the miniature tube versions of the All American Five radio - the 50C5 output tube and the 35W4 (?) rectifier - were the usual suspects. Nowadays tube radios, etc., seem to be showpieces and not actually used, with those ancient capacitors continuing to age while the tube filaments remain intact; so, today at least, the old tubes last way longer than those ancient capacitors! George P.S. The All American Five in my garage is still plugged in and still works fine at almost 50 years of age. Likely had a tube or two replaced over the years and little else. Do you remember that many stores had tube testers and some of those stores sold tubes too? I reckymember them. I'm old enough to remember those well. I had a beast Hallicrafters short wave tube radio that I'd stay up much to late listening to. Good memories. |
