The conduction cooled '250s I've used (out of Pye airband
transmitters) had a BeO block between the anode and
heatsink, but the bases were the same as used for air cooled
valves, except for the addition of a finned heatsink to help
keep the grid spigot cool . It was one of the (AEI brand) I
used in the hipot test.
