4S “The Black” Tube Preamp

This the third Super Simple Single Stage (4S) Tube preamp I have built. Dubbed “The Black”. The schematic is quite different from the original. Thanks Matt. Best sounding so far and supporting a Golden Dragon 12AU7 tube. The preamp still runs from a 24VAC wall wart and same PS as the other two builds. Big bass and detailed mids.

See my post about The Black - 4S preamp MKIII for more information.
