[AMPS] Nichrome wire and tube chimneys!

?   Bob:  Any opinion about the use of vertical air flow on horizontal
cooling fins.?

The lip at the top of the Eimac chimney turns a portion of the air
90 degrees to pass horizontally over the fins of the plate cap.
Eimac refers to the socket, chimney, and anode cap as an
"air system." I suspect a significant amount of engineering went into
the development of these three parts to work in concert with efficiency.
