Unison Unico DM amplifiers, of the older chassis design.
Same output device complement as the newest version.
It's stable down to a two-ohm load and has internal clamp protection against short circuits.
This amplifier may be used as a stereo amp, 150w into 8 ohms or bridged to 500w mono output.
Single ended or balanced input. Formerly used to drive stacked JSE 1.8, they're overkill for my Troels Quattro pair.
HUGE transformer, 40 pounds as shipped in the original double box with manual and power cord.
115Vac version.
