What else to know about the Conrad-Johnson MF-80?

"The MF80 was the first solid state power amplifier bearing the conrad johnson name. It was soon followed by the very similar, but more powerful, MF200 FET. These amplifiers were the result of more than a decade of research by conrad-johnson into the application of solid-state devices to the reproduction of music.

The MF80 & MF200 used a similar circuit and differed in their power output-the MF80 delivered 80 watts per channel RMS & the MF200 delivered 200 watts per channel RMS. FET's (Field Effect Transistors) were chosen as the basic circuit element of these designs because of their absence of the annoying odd-order harmonics that plagued so many transistor designs. Minimal negative feedback was used which obviated the typical overshoot and ringing associated with the ""transistor sound"" of other amplifiers. Parts specification met cj quality standards throughout. All capacitors were polypropylene and cjd polystyrene with the exception of the power supply filter caps. All resistors were 1% metal-oxide deposited on glass construction.

The MF80 & MF200 achieved astonishing results for solid state designs - often compared with the top tube amplifiers of the day." - Conrad Johnson
