By the way. Despite metal idlers being favoured, I'm fairly sure the plastic items are at least as good if not better. They are more inert for a start, so less prone to resonance or transmitting vibrations.

It is impossible for anything digital to sound analogue, because it isn't analogue!
They don't seem to be favoured on LencoHeaven for some reason Geoff.

Probably!
I was thinking rectangular section 57mm i/d rubber (not silicone) 'O' rings with the outer face accurately ground to a finely radiused 'V'.
I can probably cut suitable rings if I can find unreinforced pure rubber hose the right width. Or 4.5mm sheet.
And, yes. You can grind rubber. That's how some turntable belts are finished.

Please keep us posted on this one mate . I for one would certainly be interested .

The rubber on the outer edge of the idler wheel can be prone to flat spots which can cause issues with noise on the platter. To get these sorted I believe the options are:
1 New idler wheel
2 Idler wheel rubber is ground back to perfect even depth on the idler wheel.
I think Dom at Northwest Analogue can do this.

Another night, another update! IT'S ALIVE!! IT'S ALIVE!!!
Tonight has been about getting the basics of the deck sorted. Speedy Steve finally came through with the excellently made Alphason collar mount, it fits and works perfectly with the '75.
Tracking weight. The JICO SAS replacement stylus for the M55E is quoted as tracking from 0.75g to 2g, have you tried doing 2g with this cart? Maybe it's because the collar is only held in place temorarily, but I was getting mistracking at 2g so I'm down to about 1.6g until I can get the collar properly mounted and fully level. The Alphason is shown to be tracking here at 1.9g but it's more like 1.6g.

I get Dr. Feckhart's protractor out and checked alignment, the Alphason was spot on for Lofgren A, so no problems here. A few other basics checks revealed spindle to pivot distance of 211mm and measured effective length at ~228mm. Tonearm looked pretty parallel to vinyl but the mounting collar for the tonearm is not properly mounted so this is bound to be off. Still makes a nice sound!

The deck is at least level!

The first picture of the deck actually playing a bit of music. I'm now back down to single platter for the moment and as mentioned I will be fine tweeking the setup of the deck of the next few days/weeks. Usual stuff like offset and overhang angles, are all to be checked out and of course I'll do some pix to assess how parallel the cart to vinyl appears. I also decided to ditch my old Lenco mat and swap for my Garrard 301. The old 301 mat was king o' the crop for ages before being ousted by the Tenuto gunmetal platter mat, so I kinda figured that it might give the '75 a little extra dampening. I'll probably do a little experimenting with my copper record puck as well to see if that helps the musical presentation.

I decided I wanted to clean up the power supply going into the '75. This is the Russian power filter I bought off eBay for £55 it has the same circuit that Lamm amplifiers use to filter power supply.

Right that's it for tonight I'm ker-Knackered!!!

Very nice Andrew . I look forward to your findings in all of this work .
The new plinth looks very nice indeed.
I've been tracking mine at around 1.5g . I'll put mine up to 2g when I get a chance and report back .
