Commentary
Pre-main amplifier which is an improved version of Model1150.
A low-row-cage type coupling capacitor is used in the pre-amplifier section to pursue linearity.
The control stage is equipped with a variety of functions to cope with the diversification of program sources and environmental conditions.
The power supply section uses a 56,000 μ F large-capacity filter condenser.
We had two wood cabinets, Walnut and Mahogany, and an adapter for rack mounting as an option sold separately.
