Hello, first off, I've been there before myself.To my knowlege, there is no direct substitute
for this tube, short of changing the socket style and re-wiring it to fit another tube type that
will spec-out the same or better. If I recall, the 8950has a 12.6 volt filament and was a tube used
in the last of the tube powered mobile (police, fire, ham)radios.It is still available although quite
scarce & expensive. You can buy it at Antique Electronic supply (Tempe Arizona)and while you are at it,
you can buy their re-print of the 1973 G.E. Tube Manual. The 8950 is listed in there. Also, the 8950
was not specifically a "sweep tube" it was indeed designed for two-way mobile communications.

if using even numbers of tubes you can use any of the 6.3v 12 pin compactron sweep tubes.
just hook the heaters in series on 2 of them.
then hook up the pair to the 12.6 line.
8950=6lb6 with 12.6v heater and an extra cathode pin.
