TUNG-SOL 6CD6GA — BEAM PENTODE
COATED UNIPOTENTIAL CATHODE. HEATER 6.3 VOLTS 2.5 AMP. AC OR DC. VERTICAL MOUNTING POSITION (horizontal permitted if pins 2 and 7 are in a vertical plane).
GLASS BULB T-12, JEDEC CAP C1-1. Base B8-110 or B5-123 short medium shell 5-pin with external barriers. BOTTOM VIEW BASING DIAGRAM JEDEC 5BT.
Basing labels: G1 (pin5), P (cap), G3,K (pin3), H (pin2), H (pin7), G2 (pin8).
The 6CD6GA is a beam pentode designed for use as a horizontal-deflection amplifier in television receivers. Features: extremely high perveance, high plate current at low plate and screen voltages, high ratio of plate to screen current.

  Grid #2 Voltage ........ 100 / 175 Volts
  Grid #1 Voltage ........ 0 / -30 Volts
  Plate Resistance (approx.) ........ - / 7200 Ohms
  Transconductance ........ - / 7700 µmhos
  Plate Current ........ 230 / 75 mA
  Grid #2 Current ........ 21 / 5.5 mA
  Grid #1 Voltage (approx.) for Ib=1.0 mA ........ - / -55 Volts
  Triode Amplification Factor ........ - / 3.9
Footnotes: D=applied for very short interval so as not to damage tube; E=triode connection (screen tied to plate) Eb=Ec2=175 V, Ec1=-30 V.
SIMILAR TYPE REFERENCE: The 6CD6GA may be used as a replacement for the 6CD6G; differs by straight-sided T-12 envelope and increased max ratings for plate dissipation, pulse plate voltage, and bulb temperature.
