Western Electric 316A UHF Triode Tube  
Written by AnubisTTP on 2013-03-22  


The 316A is a high power UHF triode in a large, spherical envelope. Commonly called a 'doorknob' or 'UFO' style envelope by collectors, this tube was manufactured by a number of vendors including Tung-Sol and General Electric; the example shown here was produced by Western Electric. The two cooling fins on the anode help to dissipate heat from the tightly packed components around the filament.
