Kenwood KD-500
Kenwood KD-550
(1976 - 1978)

Not yet Kenwood's big push toward high-end but nevertheless sporting what was then becoming a widespread trend : composite materials !

So, the base is made of plastic granulates, stone powder and mineral fibers, all pressed together under high heat.
The underside is formed so that no possible resonating cavity remains. This composite was later on used on lower-end Kenwood tables.

Available as a drive (KD-500) or with a stock tonearm (KD-550). I'm sure the KD-500 would be a nice affordable drive to re-discover.
