Box O Vacume Tubes

[ericcarson]

I have a box of assorted vacume tubes, about 30-40. some dont work but the rest I either cant test or I do not have the numbers for my tester. Anyone interested?

[L. Daniel Rosa]

Sure. Do you want to get rid of them all at once, or a few here and a few there? I don't know if I want to spring for the shipping on 30-40 without knowing what they are (some are bulky). A little info like what are the three most common numbers will help move them fast.

Okay I will look, Right off I can tell you there are quite a few of 6A type and some of the omes with a plastic base, like 2 7 pin high voltage rectifiers stuuf like that but I will have more info tomorrow (3-14)

My brother gave me a box of tubes he found during some home renovation. Turns out that it was old tubes that were pulled to fix TVs, so all were bad -- open heaters, low emission, shorts, etc. Things to look out for (bad things) are tubes that aren't in boxes or tubes in boxes that don't match in either type number or brand.<p> Unless the tubes are NOS (new old stock), they likely aren't worth fooling with unless they're really old or rare and still have some life in them.

Well soory for the delay, I got the numbers off off them and there are quite a few:
9J10
6BAH
6AW
6AU
6BN
1X2A/1X2B
6BK5
5AQ5
6AFUA
618A
12R5

I bought a box full of tubes once and got burned as well. They were all old pulls. But If any one needs some good tubes check out http://www.fairradio.com/ I bought my last pair for an old amp there , A lot cheaper that other places on the net. They have new and used (pulled and tested ) from old not worth fixing equipment.They also have tons of old radio and test equipment. Some Military surplus. Allan
