Here is an very old shot of the ML3 I had to repair
200 W/channel at 8 ohms, 400 W/ch at 4 ohms, 800 W/ch at 2 ohms
It opens up like a clam very thoughtful design for techs and you can power it up like that, it was so big it wouldn’t fit on my work bench, so I used the kids homework table. Some 24 bi-polar outputs per channel 2 x massive transformers, true dual mono amp.

Didn’t come within cooee of the 25w ML2 monoblocks for sound quality
I just find it quite admirable that a class A transistor amplifier from 1977 still can on sonic grounds (the most important quality/criteria IMO) outperform so many current production amplifiers.If you look at it nearly all tube amps today are based on the 1949 Williamson circuit, https://www.preservationsound.com/wp-content/uploads/2012/01/WilliamsonAmp_1947.jpg
Similar can be said about transistors, especially Matti Otala’s, Nelson Pass, John Curl, etc etc designs
