Based on a Classic 70’s preamp, the 12k72 model is a high class preamplifier which contains a module per channel. The main feature of these modules is a sound completely clear and transparent, with deep bass and an extremely natural treble.
The 12K72 is formed by two stages, the first gain stage is set with a gain control, while the second stage remains fixed.
The output control regulates the amount of signal passing from the first stage to the second stage.
Everything inside this preamplifier is high quality: the wires, rotary switches, capacitors, resistors and connectors.
