6AU6
The 6AU6 (European: EF94) (Russian: 6Ж4П) (P/N 154-022, 154-0022-00, 157-0073-00, 157-0059-00, 154-0284-00) is an RF Pentode vacuum tube for up to ~50 MHz with a miniature B7G 7-pin base, introduced in 1946.
The 12AU6 is the equivalent version with a 12 V heater.
The 6AU6 is used in the 513, 561, 581, 585 and others as an error amplifier, in the Type 53/54C plugin, and others.
The 6AU6A is an improved version for equipment with series-connected heaters that ha controlled warm-up and heater-to-cathode voltage rating increased to 200 V. The 6AU6WA is a ruggedized version.
The 8425 (used in Type Q ) is an improved successor version.
