Pioneer MU-3000
(1972 > ?)

Very rare LP drive, contemporary of the Sony TTS-4000.
If Pioneer was very successful with its integrated record players, strangely enough, it wasn't with separate drives... Not many PL-C590 were sold and even the drive section of the Exclusive P10 (smaller sibling to the P3), if available separately is of the xxx-rare kind...
Three Hall elements with 0,8µ ultra-thin vacuum-deposited elements (a record then) and 20-pole motor, 1,7kg platter, ±2% pitch control, 60dB signal-to-noise ratio, 0,03% speed accuracy - 10kg in toto.

The MU-3000 is a bit "vintage" to look at and its specs clearly show its vintage :) We're far from the 95dB of noise floor of the P3a and no Stable Hanging Rotor yet - the ball bearing is loacted way down below at the base of the MU-3000.
