2 NOS Sylvania JAN CHS 5930 / 2A3W Vacuum
Tubes
RARE
1951 Vintage Audio Triodes
These new-old-stock
tubes have been tested for mutual conductance. On my Hickok TV-7 tester they read
61 and 63. A reading of 38 would represent the minimum recommended value. These
new-old-stock Sylvania tubes are from the same 1951 USA military production.
These very ruggedized tubes are also marked as 2A3W’s.
The 5930 (aka 2A3W)
is a power triode for use in receiving, transmitting
and audio applications. The 5930 has a T-12 bulb on a wide
base. The filament is 2.5 volts at 2.5 amps. These triodes are rare and built
to last. The end flap of one box is missing.
