Oops, mixed up a couple of tubes, my 6BK4 is very heavy leaded glass, the rubberized lead tube is a 3DR3 rectifer.

Yep, that's the one. I have at least one and maybe a couple of more. I've got a thousand tubes I haven't catalogued in my basement.

Off topic, but I discovered I've got a small RCA scope and a Kingston "Absorption Analyzer" whatever that is. Looks like a scope (has a CRT) but isn't.
