found boxes of tubes, what should I look for? - Page 2

5port · #21 11-09-2012, 11:39 AM

I inherited my uncles old tube caddy from the 60s and 70s. I already went thru it and found some NOS 12AX7s but most of the other tubes are TV replacement tubes. I assume they are not of any value? I have found 12at7s and 12au7s as listed below no others on this list.

Power tubes: 6550, 6L6, 6V6, el84, el34

Preamp/driver tubes: 12ax7, 12at7, 12au7, 6SL7, 6SN7

Rectifier: 5AR4

Look them all up. Some of the non guitar/bass amp tubes are worth a lot. For example I have a pair of 8005 transmitting tubes that were used in a particular McIntosh hifi amp.

If you find any 6550s or KT88s, I'd be very interested...very interested indeed...

I'd take any 7027's...or 7355...or 7591...

Any RCA 7025's? ECC83's, 12AX7's, 5751's. All those are good preamp tubes. I, like many would be interested in them if they test good.

Throw it all in the garbage can.

Send me an PM where your garbage can is standing.

BTW the Telefunken ECC803S/12AX7 is more worth than pure gold.

It's a pain, but test each tube thoroughly, each side of double triodes. Write all the data down. Search eBay for completed auctions. See what they're going for. The way it works, you will get more for a tube by itself, properly described, than you will for a combination of tubes. You can do pairs or quads of the same tube if that's the way it's used, and if they're well matched. Otherwise list them one at a time. Google whatever you can about your tubes. Take your time. It's a hobby that pays off. I would find a bunch of tubes dirt cheap and if it contained a few I wanted to try, I'd buy it. This will pay for a good tester in no time, plus you'll find some treasures in there as long as you don't suspect the lot of having previously been picked through, or being someone's discard pile. You can find a lot of discard piles on eBay.

A tester without its chart and instructions isn't worth diddly, unless you can find scans of that data online, which may mean you can pick a great one up cheap.

This is a fun hobby that pays for itself. Once your tester is paid up, hang onto it for life. You're really not going to make any money.

I came out of my months of tube rolling and testing and prospecting with a free tester and a perfect pair of fetish-grade tubes. Well worth it.

got bunches of both... Since posting this, I have found a third box, back in the corner, as well as numerous other electronic goodies... and in a very back corner, covered, a set of original wheels and tires for a jeep CJ3A..(the wheels were worth more to me than all the rest of the stuff)

This will give you an idea of 6SN7GT retail prices. Ignore the new production prices (Sovtek, Russian, China). http://www.tubesandmore.com/search/node/6SN7GT

Hello to Redding BTW, got snowed in there once helping a GF's family move. Pretty area of CA.

I am actually in Shingletown, 30 miles east, and 3,000 feet elevation higher then Redding
I use Redding, for a location, because no one knows where Shingletown is.
