The passive preamplifier section has just an input switch (Elma), an anti-RFI filter and Noble/Alps volume control. The power supply uses four big 63V caps for 60,000 µF of total capacitance. The output section uses two pairs of mosFETs per channel, placed directly against the huge heat sinks (see picture for details).
The location of the IEC socket for the main power is pretty unusual: it is on the lower part of the amplifier, directly under the massive 500 VA (!!!) toroidal transformer, so to avoid to run the mains cables "inside" the cabinet. Neat.

The data claim a 2x100W @8ohm and a 2x220W @2ohm output power with a 50 A (!!!) current peak.
Another peculiarity of this amplifier is that it works in class A up to 2x5 Watts @8ohm.
