Before I listed these on ePay I thought I'd offer these to you guys here. I
have 43 tubes in inventory I kept for my Drake TR-4C, and since I no longer
have the Drake I thought someone else would want these spares. Most of these
appear new, but about a third of them are used. I do not have a tester, except
for my TR-4C when I had it, and I had tested quite a few of these, new and
used, in the Drake to assure they were good. I never found a weak or dead one,
but that's not to say they're all good. I just don't know for sure and it's
not worth buying a tester. If you'd like a list just email me and I'll send
you the pdf file and a photo.
