The MS 1000 S amp offers 20 W power per channel in class A, then switches to class AB, reaching a maximum power of 150 W per channel when operating on a 8 Ohm load. The amplifier is built on a hybrid circuit - the preliminary amplification stages are made on vacuum tubes (6SN7 x 2, 6N11 x 2, rectifier 6Z4/6U4 x 1), and the output ones - on transistors.
