I plan to use it in an HF amp. Sockets for this tube are rather scarce. Has someone tried to use it in a home-made fixture?

You only need to arrange to ground the suppressor grid ring. Compare the detailed drawing of the two tubes.

The suppressor grid ring is larger in diameter than the bayonet contacts. 73 Bill w; /archives//html/Amps/2010-12/msg00163.html (12,533 bytes)

It will bottom out in the 8877 tube. But after doing that you can still use the 4cx1000A tube ( but not in GG naturally). 73 Bil; /archives//html/Amps/2010-12/msg00165.html (11,866 bytes)
