Very rare LP drive released alongwith the CS-3000 and SM-3000 - a mini-series of three(s).
If Pioneer was very successful with its integrated record players, strangely enough, it wasn't with separate drives...
Not many PLC-590 were sold and even the drive section of the Exclusive P10 or that of the PL-70L, if available separately are of the extra-extra-rare kind.
The magnificent MU-1800 is also a rarity, whether as a drive or in its integrated player version...
The MU-3000 is a bit "vintage" to look at and its specs clearly show its vintage but it was, for the time, very advanced :
Three Hall elements with 0,8µ ultra-thin vacuum-deposited elements (a record then) and 60-slot / 20-pole motor, 1,7kg platter, ±2% pitch control, 60dB signal-to-noise ratio, 0,03% speed accuracy - 10kg in toto.
We're far from the noise floor of the later 1970s and there was no Stable Hanging Rotor yet - the ball bearing is located way down below at the base.
