Hi Guys,
In the process of giving one of these a birthday for a client.
The platter rings like a bell, and the original thin rubber mat does it no favours at all. Wondered if anyone here had any substantial rubber mats (sorta like the ones graham made at one time...) that they wouldnt mind parting with ? Cork may also work ?
PM me with P&A
Any help appreciated.

I gave mine a help with a generous sprinkling of Dynamat, and a rubber ring.
And ditched the mat in favour of one that "decouples" the lp from the platter, as in a Resomat, or one of those cork dots would achieve the same.
Search Chadwick mods. Graham has done them I believe.
One of the best was to replace the thin base plate with something that gave the plinth more rigidity.

Yeah I didnt want to get too carried away applying damping to the platter as its for a client and would prefer any mods to be discreet and reversable: hence I thought a better mat. And yes will be talking to someone tommorow about a new base for the plinth to replace the chipboard one.

Or glue-on a 'stiffener' or two across the top of the baseboard. Some strips of pine would be ideal. If you have some & are DIY-handy. I did that once, for a TT table-top sub-base. (The 'light but rigid' principle.)

I haven't made any of my 'Demon' mats for a long time as the demand seemed to have dried up. Maybe I should buy some more of the reinforced rubber and whip up a few. All of the Thorens 150 and 160 series benefit from all or most of the recognised Chadwick Mods, which include the thicker baseboard, and sound deadening to the subchassis, subplatter ( not the main platter ) and underside of the top plate. The original mat was probably OK when new but with age the rubber becomes stiffer and loses its elasticity and seems to no longer work as intended. A circle of the 'shelf liner' material from the local 2 dollar shop works brilliantly but unfortunately does not look too hi tech or hi fi.
