The Clean Gain stage is a balanced instrumentation amplifier built with our DMPAs (Discrete Mic Pre Amp, 60 Volt rail).
In Class A mode, both end transistors always remain in a conducting state, thus avoiding crossover distortion.
With a slew rate of over 100 V/µs, it is capable of amplifying even fast details and high frequencies cleanly and with low distortion.
The tube gain stage is equipped with a 12 AX 7 LPS. It impresses with good noise figures and an open and clear sound image.
As decoupling capacitor a WIMA MKP type is used, which is very generously dimensioned with 2.2 µF, in order to work clean and powerful also in the bass range.
