Revision as of 06:00, 11 October 2021

The 6CB6(A) (European: EF190) (P/N 154-0030-00) is a pentode vacuum tube with a miniature B7G 7-pin base.

It is used in the vertical output amplifier of the 517, and the output coupling stage of the 112.

6CB6 and 6CB6A (EF190) are identical, except for the controlled heater-warmup time of 6CB6A.
