I take it this is a turntable with Aux out?

rather than what we would call a record player (with power amp to which you could attach speakers).

either way, it’s a good job and well beyond my skill set!

I’ve never knowingly come across such a small 3 phase motor (or perhaps that was a mistake by Google Translate?).
Domestic premises in the UK usually only have single phase.

New electronics installed and working!

The speed is adjustable, the strobe is a vintage yellow color, the electronic microlift of the tonearm... - everything is as it used to be.

But much more compact and reliable.

Compared to the old electronic junk:

A new look:
