Hi everyone, bug fan of Mr C although I know NOTHING about electronics. I am fascinated with vacuum tubes and from time to time will buy some. I just purchased one but it came with no visible number. Already tried the condensation test with no results. You can see the images of the tube on this link. removed link
Thank you very much for any help.
Welcome, first post won’t allow links. Try doing it again after a few posts. Easiest way to start, what base does it have and is it metal or glass shape does it have? A picture would show all that, but until then we can start working through it. I have several hundreds of them with little to no writing on them as well, just haven’t started that project yet.
Radios + Tubes + Scopes + Cars= Nothing better!
