Tubes?

YES- Mr A has nailed the ones that would be most desirable to an audio-tube user. If they are NOS, they could put some change in your pocket. You might try contacting Audio Classics(Vestal, NY), and asking if they would grade the tubes for you.

Here are (in my opinion) the most desirable of the lot:

12AT7 3 SYLV, TUNG, TELEFUNKEN
12AT7WB GE
12AU7 5 AMPEREX (4), RAYTHEON
12AU7A 4 SYLV, RAYTH (2), GE
6DJ8 2 AMPEREX

Oh, I forgot to add, I'm in NYC, Upper West Side.

Thanks for the replies so far. Here's the list of tubes. I had no idea how to sort them, so I just did it based on external appearance, then by alphabetical order on the designation.

Edit: the preview seems like it won't be quite readable, so here's an Excel version: http://dl.getdropbox.com/u/243/Tubes.xls

+1 for Mr A's advice. Further- The majority of musical instrument amp repairmen own tube testers, as tubes are widely used in music/sound gear. Check your yellow pages, and make a couple calls.

I'd stick to Albert's advice. It is sound, I think. Give us a list of what you have, wait for responses and go on from there.

It's also possible the tubes you've found are not worth the trouble even if they test perfect. Of the thousands built, only a double handful remain popular in high end audio.

If you list what you have, I and a dozen others here at Audiogon can tell you if they are desirable. If they are desirable it's worth testing them and putting up for sale or keep for yourself.

I would either send them and pay a small fee to a reliable Tube supplier..or Ask someone on this Audiogon site that has knowledge and owns a calibrated tube tester to test them for you.....Other than that its not worth taking a chance unless your willng to take that risk?

There are 2 options.
1. Use a tester, but some only give you a good-bad decision, no idea of how good. Its been a long time since they've been at the five and dime (a long time since there has even been a five and dime), but you may find one at your local independent hi-fi or tv repairman, or if you post your location, someone here may volunteer.
2. Sub them in to a component that uses the same tube type, but again, that will only give you a go-no go decision
