Not long ago, a friend and I were at the antique show at the Ohio Expo. A vendor had a couple of Zenith Trans-Oceanics sitting on a table for sale, and my friend commented that he had one when he was a kid in the 80s and doesn't remember them being in such bad shape like they are now. I told him "That's because the device was only 30 when you had it, and gramma probably just retired it not that long ago. Now? They're 70+" He was yah, you're right. They're approaching their century mark in some cases. I had similar, all that old tube equipment from the late 50s and 60s...worked fine for the most part. That RCA WV-87B multimeter? Sure, it was as accurate as an analog meter could be, but now you need to replace everything in it because everything leaks like a screen door on a submarine, and those roundy carbon comp resistors are now 5x their listed value. People getting hold of these items now never had a time when they could reasonably expect to pick up and use the stuff with no work. Just interesting to think about how time has passed like this, and the effects it has.
