[Boatanchors] P&H LA-400 linear

[Rob Atkinson]

I think there are often a lot of 4-65As on eBay and the socket is used
by a few tubes.  Fair Radio sold 4D32s--it might use the same socket;
can't remember for sure.  What's nice about the 4-65A is that you can
put a lot more Ep on the anode.  4-65s are cheap usually because
demand is low.
