Posted this on a couple other forums, so I guess I'll post it here too:oops:
I was cleaning out my grandmas attic and found a large assortment of old tubes and a bunch of old capacitors from when my grandma used to mess around with old tube radios and CB's. First question is are they worth anything..Second one is how can i tell if they are good..Also if anyone is interested in doing some trading inbox me..

They're no good. Package them up and send them to me. I'll dispose of them free of charge. ;-)
But seriously - looks like there could be some quite useable tubes there for someone who appreciates tubes.
(I wish I had a grandma with an attic like your grandmas)

the stripey components are resistors... the different bands relate to values...
the big brown waxy one looks like a cap... the value will be written on it.... ;)
go CB, granny...

Great find !
Are thay worth any thing?
Thay made alot of tubes back in the day only a few are worth anything today. (some are worth a lot) The other poblem is sometimes people swapped a tube then stuck the old one back in the box. Good tube or bad thay look the same so it's hard to tell.
I'm not saying there worthless but don't plan a trip to Europe or a new Jag.
Could you post a list of what you have.

Old 6V6 tubes must be worth something since they are still a popular tube. Nice find. What was Grandma's handle?

A list of what each tube box is labelled would be a start.
The main markets now are for musical instrument tubes, hifi audio tubes, and radio tubes. Often what you find are a lot of old TV tubes.
But beyond that each would need to be opened, and the contents examined to be sure it matched the label, and then (ideally) each would need to be tested to determine if it was new, at least still functional (a 'pull'), or DOA.
If they are un used (NOS), you might have some decent money, if fuctional pulls they may still bring a few bucks. TV tubes, in any condition, aren't much more than curiosities.
edit: BTW that 12sy7 is a frequency mixer for superheterodyne receiver, so matches her hobby quite well.

I meant to put when my grandpa mess with that stuff.His handle used to be Treasure Hunter.I remember when I was a little kid and he had a power amp hooked up to his CB and when he would hit the button it would squeal alittle.I always liked that sound.he would talk to people all over the place.Still trying to find out how to test them.If there no good it doesn't matter what's in the box.

You need to find someone with a tube tester. Try calling various repair technicians in your neighbourhood first. If they can't help directly they may be able to suggest someone who they know who can.

A newly found stash of tubes is a wonderful thing. many were for radios, even more for TV sets. Only a dozen or so tubes are really any use for guitar amps.
The best thing would be to make a list of what tube #s you have, and who the manufacturer was. Some are worth more than others. For example, a 12AX7 pre-amp tube is in demand. A GE one is OK. RCA is better, and a Mullard in workingorder can be worth some real $$$ to the right person. As mentioned before, many amps, inclucing many classic Fender amps used a 6V6 tube. On the other hand, I have a box full of NOS TV tubes I cannot give away.
If you make a list, we can help you id what the tubes are for, and if they are worth saving/selling for guitar amps. I would argue that US made tubes were the best in the world in the 50's and 60s. GE, RCA, Sylvania, etc are no longer making them. Once they are gone, they are gone for good.

take them to your local Rexall drug store and test them on their tube tester. it's usually in the back across from the soda bar.
