Roy wrote giving a list of tube shield model numbers for the
various sized tubes in the R-390A. Excellent info!! Thanks!
The 9 pin size used for 5814s is the 6020B.
Rich says he has model 6015B shields for sale. They are shorter,
about 6AK5 height. I've been using some for 5814s (and other
tubes in other equipment). Although they are short (and look
funny with the tit of the tube sticking out) they seem to
work fine.

Bob wrote asking what the 6015B was designed to fit.
Any 9 pin mini of 6AK5 height. I think the 5842/417A
is a 9 pin of that height, and I recently saw an Amperex
thyratron in that package.

Hope this helps.

Gary
