My vacuum tube collection

last photo ←

This is my collection of vacuum tubes, these were all given to me and are original. For a very long time Iv'e wanted some vacuum tubes and then my mom brings home a big box full of them and now I'm very happy! most of them are from Sylvania, then RCA, then realistic lifetime tube, GE, and a few others. I believe most of these still work, when unboxing them, I only saw two that were labeled bad, I wish I had a way of testing them without ruining them. I was a bit dissapointed that the boxes or tubes didn't have dates on them except for one that said 11/59.

You can check the filaments with a multimeter. Just a basic continuity check. The tube can have a good filament and still be bad, but the filament is the most common part of a tube to fail. A full check requires a tube tester, which is an expensive piece of equipment nowadays. If you want to look them up, here's a site with a lot of tube datasheets. They can tell you what each tube is designed to do.

I have tested a few of the tubes filaments with a 5V 2.8A power supply and most of them seem to work, I just emailed a friend of mine that works at a TV repair shop to see of he has a tube tester. Thanks a lot for that website! I've only been able to find 3 data sheets so far on other websites.

I have absolutely no use for them at all at the moment but I was hoping i could make a vacuum tube tesla coil or maybe a radio. I'll probably sell a few cause their worth a lot of money.
