[Milsurplus] VT-191 Socket

[Michael Bittner]

Richard,
Yep, you are probably right, but I was thinking of using it in an HF application.

  Probably not, and would be undesirable because any insulation at high impedance points (grid and plate) will introduce losses at UHF.  At UHF "no socket" is better.  The BC-645 is the only application I have ever seen for the 316-A

    As used in the BC-645 IFF Transponder, there is a socket for the filament pins only, while the grid and plate pins plug directly into receptacles on the quarter-wave tuned-lines of its ultra audion resonant circuit.

    A stand-alone socket would probably be T-shaped with the filament pins in the vertical part of the Tee and the grid and plate pins at the ends of the horizontal part of the Tee.  http://www.radiomuseum.org/tubes/tube_vt191.html
