This is the first amplifier designed by Mark Levinson, introduced in 1977 (- 1986).
It's a 25 watt/channel mono amplifier, operating in full class A. The matching preamplifier is the ML-1.
George Yiannakopoulos sent me the following very valuable information :
ÇTransistors : The transistors you are questioning below 2N5686 and 2N5684 are the original parts for the ML2 and may be replaced with Motorola MJ15024 and MJ15025. Please note, that both channels need to have the negative and positive output transistor changed.
