[Amps] Blowers for metal-ceramic tubes

[jeremy-ca]

Good work Ian.

Ive been using the nice technical information plus charts published by Bill 
Orr, W6SAI, in the Sept 1967 QST. A very informative article a bit over 6 
full pages. It also uses several tubes as examples that are still very much 
with us for homebrewing.
