The ML-3 is a hell of a beast ! With its weight of 52 Kg (116lbs) and its depth of 62cm (20½") the only place where it can fit is... the ground. Hopefully, working in class AB, it doesn't need that much electricity most of the time. The only question is, what kind of loudspeakers may need this POWER amplifier?
This amplifier is made of exactly 2 mono amplifiers, each on each side, with the two big (1,2 KVA) toroidal transformers put in the middle of the chassis next to some 36,000µF capacitors (100V). It can output 45 Volts at 30 Amperes: you'd better use fat speakers cable cables.
Pro and Cons
| Pro | Cons |
| Stereo, high power. | Large and heavy. |
| Can drive any speaker. | Lots (20) output transistors which can be expensive to replace. |
| An engineer delight :-) | Specific (non standard) connectors used. |
