ECC35, 6SL7GT, CV569, CV1985, CV3985, VT-229, SMALL SIGNAL, OCTAL

The 6SL7GT is a medium impedance double triode with high gain. It featured separate cathodes and was designed for use as AF voltage amplifiers, phase splitters and where required as a cascade amplifier of very high gain. This Octal triode is favoured for many guitar and classic valve amplifiers, however, it is surprising which other well regarded and modern exotica also demands fine devices of this type.

The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 62 mm tall.
