Commentary
A stereo power amplifier developed by Altech to drive its own speaker system under ideal conditions.
The circuit is of OCL direct coupling configuration, and high output of 200W + 200W in stereo and 800W in monaural is possible.
Die-cast is used for the front panel so that it can withstand severe conditions as a professional machine.
In addition to the pin plug, the input is also equipped with a canon plug as standard.
The balanced input transformer was optional.
