Hi All,

I'm about to build a 4CX1500B amplifier for 2m.

Most, if not all, descriptions are blowing air into the enclosure on the
base side of the tube and the air goes through the socket and finaly
through the anode chimney.
For several reasons i would like to blow into the anode enclosure
directly onto the anode, the air would then go out through the anode
chimney. Only a small part of the air would cool the base of the tube
through small holes in the anode/cathode separation.

Is that a stupid idea ? Is there any reason not doing so ?
