Part LP12, mostly Kuzma.

Take a look at the motor on your Thorens and let us know what it is. it looks like a twin phase Ac unit, just measure the two voltages.

Hi sq

I think it well might be.
I did look inside a while back for a 'nose'...
...but screwed the bottom back on QUICKLY !!!...
...since I hadn't realy a clue what I was lookin' at !

I will have another look...soon.
We are OK with mechanical stuff here at Space Egg...
...I totaly understand what you said about the spindle-pressure sq...
...bit like 'backlash' on a lead-screw, sort of thing.
Mmmm....

Cheers.

Si.

The LP12 motor is similar to that of my Thorens TD-150
in so far as it actually runs on 110V.
Half the voltage is dropped by a resistor (see attached
image) when operating with 220V.

If using a transformer, would it make sense to use
220V:110V and omit the resistor ?

What would the benefits / drawbacks be ?
