Kenwood KA-9150

1 9 7 7 1977
1 9 7 8 1978

One of the pinnacles of what "healthy audio gear" meant... when knighthood was in flower.

I believe the KA-9100 to have been an export-only item but it was the heir to the Model 500, Model 600 just the same. A bit more affordable, therefore much easier to find.
The KA-9150 is the same amplifier finished with a beautiful warm grey/bronze anodization ; the version is extremely rare.

The next step one was the KA-907 but all of these aren't really different, just steps in refining a formula.

With less romantic curves, the KA-9100 was and still is like driving a Jaguar 420 - with the overdrive
And for so much cheaper nowadays.



Do read the USER section for the circuit details - reading is good for your health !

Also a complete restoration at Curt June's.
