Notes

High-perveance beam power tube for horizontal deflection in color TV. Compactron 12-pin base (Duodecar B12C).
TDSL shows two operating conditions: (1) line output at Va=130V, Vg2=130V, Vg1=-20V giving Ia=100mA, Ig2=4mA; (2) line output at Va=60V, Vg2=125V, Vg1=0V giving Ia=800mA, Ig2=50mA.
Very high peak anode voltage rating (6500V) for horizontal deflection flyback pulses.
Maximum cathode current 400mA average — heavy-duty deflection service.
