6CH6 tube (electron valve miniature output pentode)6CH6 tube (electron valve miniature output pentode) Manufactured by Brimar and STC
The Brimar type 6CH6 is a miniature high slope pentode. Its high anode dissipation and current rating make it suitable for working into loads of low impedance and self capacity. 6CH6 is a commercial equivalent of the CV4055 RATINGSHeater Voltage 6.3 V Heater current 0.75 A Anode Voltage 275 V max Screen (g2) Voltage 275 V max Anode dissipation 12 W max Screen dissipation 2.5 W max D.C. Cathode Current 60 mA max Max. Peak Cathode Current (Absolute) 1.5 A max * Max. Control Grid Circuit Resisitance 0.1 MΩ † * The duration of circuit flow must not exceed 2µ sec. and must not be greater than 5% of the duty cycle. † this value may be increased to 220,000Ω if autobias is employed.
