Part of the magnificent Toshiba System 15.

The SC-M15 is a DC amplifier encased in a one-piece diecast aluminium chassis with only the toroidal transformer's and 2x 10,000µF capacitor's top shining through in plated chrome.
This look was loosely derived from a big and intriguing mid '75 2x 150W prototype named SC-910.

Input and pre-driver stages are in Class A, output in Class B ; both stages are fed from two different trafo windings.
A (moderate) BTL use is possible, amounting to 1x 90W under 8 Ohm load and between 20Hz and 20Khz.
Low-inductance V-Type film condensers, 70µ PCBs, high-quality power transistors, gold-plated connectors - audiophile goodies.

Mostly, a truly exceptional design, as simple as efficient and striking, which shines however better in its original champagne color than in its later black mode.
Available under the normal Aurex name in Japan, Toshiba elsewhere but there seems to have been "Aurex" export versions as well.

I want I want I want. I have.
