Kenwood model 600

New State-of-the Art Engineering with quality as the Only Parameter Puts the Model-600 in a Class by Itself. Featured are High Power. Low Distortion and Two Independent Power Supplies.

The Supreme Series was sold as an exclusive, 'special order only' line in most of the world (some but not all Supremes were available as parts of regular lines in Japan, Belgium and Germany), and was only available from some exclusive dealers in Canada and Califiornia. I am sure many regulars on eBay will feel bad for either missing these or letting them go for a song, as they are the absolute pinnacle of Kenwood's amplifier building knowledge, which has remained largely unsurpassed to this day - these amplifiers are the progenitors of all sought after dual-mono Kenwoods.

Features

Adoption of 3-stage differential amplifier and parallel push-pull ICL, OCL, DC amplifier which employs FET in the inital stage.
