Tubes so rare you would will probably never see in your lifetime, but if you do don't pass them by. Some would think they are fake, but they are real. When these first came into my possession I could not find a picture anywhere on the net of these things, just an old advertisement with a almost hand drawn picture.

There is a sight on the net called Tube Distinctions with the history of the KT88 tube, they have now used (with my permission) my picture as they did not have a real picture of these tubes

What they are, are the very first and second production runs of the KT88 tubes. The Bakelite base pair are first run from 1957 The metal base are second production run 1958 still with the same style glass but different base.

The 3rd style is the KT88s you usually see today

Mine did come in the original Osram boxes with inserts and were NOS An incredible find!

Just a tube tip for you GEM seekers
