Notes

Base is Miniature Button 9-Pin (JEDEC 9BD). Brans Vademecum table IIf lists 6V3(A) with equivalent PY71.
MIL-HDBK-213A classifies as 'Receiving diode, damper' and lists 6V3A as the other number for 6V3.
GE Essential Characteristics lists base as 9BD for both 6V3 and 6V3-A.
Datasheet is marked 'TENTATIVE DATA' and covers the 6V3A. The 6V3A is an improved version of the 6V3.
DC component of heater-cathode voltage must not exceed 750 V with heater negative. This is a high Vhk rating suitable for horizontal-deflection damper service where the cathode swings to high B+ levels.
The tube should be adequately ventilated as with other power-handling tubes.
Sams Substitution Handbook lists EY81F as a substitute for 6V3.
Damper service ratings: PIV 6000 V, peak plate current 600 mA, max DC output current 135 mA. Half-wave rectifier ratings: max AC plate voltage 350 V RMS, max DC output current 125 mA.
Filter input capacitor limited to 20 uF in half-wave rectifier service. Minimum total effective plate supply voltage is 145 V.
