I recently came across a bunch of mostly NOS tubes I’d bought years ago for some tube rolling experimentation I tried with a vintage tube preamp. Unfortunately for me, fortunately for you, since that preamp is long gone and my current preamp doesn’t use these tubes, I have no use for them.
The tubes were all bought from reputable dealers who tested each of them and rated them extremely well at the time. I didn’t use any one of them for more than 100 hours, and many were used much, much less, so they should still be in great shape. But I do not have the equipment to provide current ratings. or even a preamp to listen to them.
FWIW, the tubes have not been sitting around loose knocking around in a box. Most of them came to me in those flimsy little individual boxes. I didn’t think that offered much protection. So each tube was sponge cushioned in its own plastic pill bottle, and kept in special storage unit (shown in photo) to keep them protected. I will ship them to you in the same cushioned pill bottles.
Everything sold AS IS. Asking prices listed below. Shipping to CONUS only. Add $4 shipping.
