12AU7A Tube

The 12AU7  (European: ECC82) (P/N 154-0041-00, 154-0287-00) is a dual medium-μ triode vacuum tube with a center-tapped filament for use in either 6.3 V / 300 mA or 12.6 V / 150 mA heater circuits.

It is likely the first tube manufactured with a B9A (Noval) miniature 9-pin base (from 1946).

The 5814 is a high-rel version with increased heater current.
