Posted by zac on Sat May 30 20:28:57 2020, in response to Re: [PHOTOS] Lexington Ave. el, posted by Elkeeper on Sat May 30 13:19:39 2020. Tubes were designed to last, except that early TVs were so hard on them that they failed constantly. I have tube audio equipment and haven't had a tube go bad in years. What usually does go bad is the socket. They oxidize and don't make good contact with the tube pins so you think you have a bad tube.I still have an old Dumont TV that I tried to resuscitate. It had actually been working when the grandson unplugged it the last time, and I took it off his hands a few years later. The main problem with something that old is the caps. The old caps didn't last forever and would leak. I replaced them all and tried it out but didn't get anything out of it, and then broke both wrists in a cycling accident later that week. I never went back to it. I still have the schematic posted in my basement where I worked on it. |
