RE: 6CB5A - good power in triode mode

Posted by PakProtector on October 6, 2020 at 08:50:07:
Sounds best as pentode, g2 voltage matched to the Class A load, and driven by an E-Linear rigged EL84. E-Linear connection established by 50% taps in the primary coil. 5k a-a, or 2.5k SE. B+ or 270 and idling at 100 mA...and the plate showed no color until 115 mA idle. The LC ps filter and 866's did not drop the voltage appreciably.
cheers,
Douglas
