Preferred Substitutes ......................... 6BC5
Substitutes ................................... 6CE5
Miniature type used in compact radio equipment as an rf or if amplifier up to 400 MHz. Tube requires miniature 7-contact socket and may be mounted in any position.
The two cathode leads facilitate isolation of the input and output circuits thus helping to minimize degeneration.
