[R-390] Tubes

[Bob Camp]

Hi

On the R-390A you can thank the people running the DOD supply process  
in the mid 1980's. They bought an enormous number of tubes for the  
R390, essentially none of which ever got used. Unfortunately the  
ballast tubes were in another category than the vacuum tubes and they  
didn't get in on the mass buy.
