ECC82 / 12AU7 audiotube
€ 45,00 – € 99,00
The ECC82 high impedance amplifier triode was designed specifically for audio use and has a high amplification factor of 100. Mullard describes the ECC82 as a high μ double triode, having separate cathodes, primarily intended for use as a resistance-coupled amplifier or phase inverter.
This valve is still found in today’s designs of hi-fi audio amplifiers. In the classic Mullard designs of the 1950s and 1960s, the valve’s two halves were used as second-stage amplification and cathode coupled phase splitter.
The phase splitter was required so that the push-pull output stage was driven correctly.
The thin glass tube envelope is 21 mm in diameter and, excluding the B9A base pins, is 48 mm tall.
