4 Type 837 aka VT-101 Vacuum Tubes

1940’s Vintage 12-Watt Pentodes

Hickok TV-7D/U tests read 82, 85, 85 and 86. A reading of 50 is the minimum recommended. I believe these unbranded tubes were made by RCA.

 

The 837 (aka VT-101) is a transmitting pentode. The heater is 12.6 V, 700 mA and it may be used at full input up to 20 MHz and at reduced input up to 60 mhz. Plate dissipation is rated at 12 watts.
