[Amps] 3CX800A7 Orientation

[Larry]

Bob,

My Eimac data sheet for the 3CX800A7 (dated 1 Dec 83) on page 3, mechanical:

"The tube may be mounted in any position. If it is operated in an 
inverted (anode down) or horizontal position the SK-1916 chimney clamp 
assembly should be used for reliable retention."

BTW the thing needs 33 CFM @ .88 inches water for cooling, assuming 50° 
C and 5000 foot elevation. How you gonna get that in a MLA-2500?

73, Larry
