Tungsram TKC1 directly heated battery triode using a 2 V, 0.065 A filament. Published typical characteristics at 90 V plate: transconductance 0.4 mA/V and plate resistance 60 kΩ; at 135 V: transconductance 0.6 mA/V, plate resistance 40 kΩ and amplification factor approximately 25. Promoted values use the 135 V operating point.
