Fellows,

Old war stories of the Marines at Phu Bia setting the R390's up on end and 
heating ration can on them when we locked down in bad weather or just plain 
rainy nights.

They be hot. Do the math on just the filament current and see how many watts 
of heater you have operating. The guys are right, get the fan on them. It 
really does help.
