Tubes Asylum Questions about tubes and gear that glows. FAQ |

Hello,
I bought the tubes (link below) and I am trying to find out its history. I have a considerable amount of Red bases RCA's 5691 and some branded GE's. This is the first time I saw a black base.
Any tips where I can read about them?
Thanks you very much.
regards,
Abe
