Should be plaster? That's where the name comes from (the Plaster of Paris platter and filling inside the framework, that gives it its weight.

The sensitivity to hum varies with older Deccas. I found it not too bad. The Rock has a thin 'skin' of steel filled with a hard plaster like material If I'm correct (similar to the Opus 3 Continuo), so the amount of steel may not be anough to cause problems.
Yes it's only the plinth that has the metal skin, the platter will be fine
it should be here tomorrow,any tips on alignment,with it having no cantilever as such do you just align the diamond?
DECCA carts are something magical, I remember getting my Maroon back from John Wright and being completely bowled over. I now have a DECCA II and a 78 and they all have something to offer.
The top of the body is flat and should be parallel to the record when the stylus is lowered. Some experimentation with arm height may still be useful though.
Alignment can be challenging as the diamond can be very difficult to see on an alignment template. On the Rock this is compounded by the paddle arrangement. It may just fall into place, or like my retipped Blue on my Rock, take the best part of an hour to achieve success.
Good luck!
oooh its here! :D
first impressions are its big and heavy, luckily ive got another counterweight because the standard alphason hasn't got enough weight.
i had to go to get some more cartridge mounting bolts too.25mm just does it.
strangely reminiscent in shape of the 2m black
