There are hidden two pure Class A amplifiers with the output power 2 x 40 W / 4 Ω and a Class AB amplifier for a subwoofer inside the tower.
There are toroidal transformers and circuits working with big currents in the bottom part. There are circuits for processing voltage signals above. There is a main volume regulator (Black ALPS) and a subwoofer gain regulator in front.
All conductors leading active voltage and power signal are very short to eliminate crosstalks and to prevent degradation of active signal.
Outputs and inputs terminals WBT illustrate uncompromised constructional resolution.
