About the LA150 MkII
The Joule Electra LA-150 MkII is a tube line-stage preamplifier (no phono section) using a Mu follower circuit with NOS 6350 tubes in the gain and follower stages for low distortion and high linearity. It is a dual-mono design with separate tube voltage regulation for each channel, using 6EM7 regulator tubes and OA2 (or Zener diode) voltage reference devices. Overall gain is relatively low (around 11 dB), with internal jumpers allowing limited adjustment. The preamp provides four high-level inputs (CD, Aux 1, Aux 2, Tape) and two output sets, with volume and balance controlled via remote. It is voiced to be neutral yet lifelike, with clean treble, detailed midrange, and solid, authoritative bass.
