Spacers for Rega P3


Am I the only one who thinks that the tonearm in the Rega P3 is mounted a bit too low ?
It seems that it needs to climb a few mm on its way to the record.
The solution is very simple: a spacer... but wouldn't Rega use a spacer on the stock P3 if one was needed ?
Should I add a spacer ? What size ? 2mm or 4 mm ?

Thanks for the Thorough reply.
Will do as you suggested.

By the way, How tight should screws 1 & 2 in this picture be closed.

I recently installed the Isokinetic cardas rewire kit (excellent upgrade) and had to mess with them. I ended up closing them in a way that allows me to adjust counter weight but use a bit of force in order to do it. I mean...is there a torque figure for that ?
Doug,

The result of your card test is 2mm.
The mid sounds much better now. Could 2 mm have such an effect ?
I'll order a 2mm spacer.

Apparently! Why doubt the evidence of your own ears?

Technically, if you think of it from the perspective of microscopic stylus riding inside a microscopic groove, an arm change of 2mm is pretty massive.
