Notes
6J11P is the Latin transliteration of the Cyrillic designation 6Ж11П.
Quality suffix variants (6J11P-E) exist — only the base designation is catalogued here.
Extremely high transconductance (up to 40 mA/V) — one of the highest-gm small-signal pentodes.
The E280F is the Western European equivalent from Philips/Mullard.
Primarily used in oscilloscope and instrumentation amplifiers requiring high gain-bandwidth.
