Cleaning out an attic, and found a ragged box filled with old radio and TV tubes - there are both small and large ones (I guess the large tubes are for TVs?) Some are loose, others in boxes, most in good shape.
Can anyone use these? I could try to box it up safely and send it wherever.
Here’s a pic I took with more than half of the tubes out of the box (so there’s at least twice as much more)
At the least the ones still in their packaging are probably NOS (“new old stock”) and can be sold if testing verifies they are good.
I assume you don’t have a tester? (I, and several other dopers, do. :D) So the value drops. List them on Craig’s List. Guess about $2 per packaged tube to get a total to ask for. Maybe start higher and if you get no takers, lower the price.
[FWIW: What I am interested in are “all American six” tubes: 12SA7, 12SQ7, 12SK7, 35L6, 35Z5.]
Check the arrl.org website to find a ham radio club nearby, they might like to have them. There are also radio swap meets listed where they might sell. Lot’s of hams still use tubes.
Thanks for the suggestions, but really was just wondering if a doper would like them for free.
Oh, and I’ll look through the dust for the the model numbers you listed.
you may be able to eBay them if they’re unused, and depending on what specific tube types they are. still plenty of tube equipment out there in the audio and music world.
This company appears to still be in business. There’s a detailed list on the site of everything they’ll buy and what they’ll potentially pay. Could get a few bucks out of them, or significantly more depending on what exactly you have.
Aw, I have a few tubes/valves lying around, and while I might even give some away for free to an electronics hacker, I would not want to sell a perfectly good tube as “craft supplies”. That’s for broken tubes.
A lot of people prefer guitar amps with tubes so there is a market for any tubes that can be used in an amp. the most common amp tubes are EL84 and 6L6 and similar types.
yep. to this day you can buy brand new tubes for audio applications. Most of them come out of Russia and Eastern Europe, and are fairly well regarded, but there are collectors and enthusiasts out there still looking for original NOS ones from e.g. Raytheon, Sylvania, etc.
I tried to see if there were any tube numbers I could make out on the boxes. I noticed the handwritten list of tube numbers. One just jumped out at me: 6CB6! It was the first tube number I memorized.
That’s the one to replace on those old RCA Victor TVs from the late 50s when the sound goes out. I swapped those out several times as a kid.
I thought it was cool to see so many boxes of tubes (radio or TV, not sure) marked Raytheon - it’s now a major defense contractor, making guidance systems for some very scary weapons!
For the poster asking about specific numbers, I did a quick look and didn’t see them on any tubes/boxes, sorry.
And, the poster who mentioned having someone use them for steampunk projects - that’s a great idea!
Is anyone here in touch with Rocketeer? Perhaps he could use these for some of the fantastic models he makes.
Again, thanks for all of the ideas,
Wallet
What, if any value vintage tubes has varies widely. Those that have some value include really old radio types (generally a two digit number) and those that were used in everything, including audio applications. 6L6, 7591, 5881, 7199, 12AX7, 12AU7, 7247, KT88, 6550
There’s also series string radio tubes: 12BE6, 12BA6, 12AV6, 50C5, 35W4
When people say they found a box of old tube in the basement, a lot of what they have are old series type TV tubes. These were developed specifically for TV sets and don’t have any other applications. Usually it will be some number other than 12, then two letters and a number. These are essentially worthless since few people collect 1960s TV sets.
