[R-390] Another tube for a NuvistaPlug.

[Kenneth G. Gordon]

A PAIR of 7994 subminis would also make an excellent low noise front-
end for a receiver. That tube has a gM of 18,000. Max plate voltage of 
100 VDC again however. 

BTW, filament requirements are 6.3 VAC at 350 mA for the 7963 and 
6.3 VAC at 250 mA for the 7994.
