REPLY:
The trouble with that approach is you have hot air blowing down over the
tube seals and socket. Not good. Anodes by themselves are relatively
unaffected to heat compared to the seals and socket.
Better to have the cool incoming air flow over the socket and seals
first and then go to the anode.
