[Amps] Tube sources

[Carl]

Absolutely correct Ian and thanks. Its been a long time since I saw the 
various writeups on the U version.

Now that I think of it wasnt 1296 determined to be too much of a stretch for 
it?

Im currently using two water cooled 3CX100's on 1296 and Im long overdue for 
more power. What are the current Russian choices?
