[MAMS] tubes for the 6155 Re:Back On 222mhz with Amp

[aa9il at sbcglobal.net]

Hello All
While on the topic off the 6155, is there a source for the 8930?
I have heard that a 4CX250 will work provided there is something
to shim it in the socket.  A long time ago, I heard of a machined
adapter for the tube.  I have an amp Im going to put
on 2m that has the original tube and I would like to get a spare
or go the 4cx250 route if need be.
