The things for vinyl record decks don't seem to be sensibly available
without self-amputation.
As long as its a decent deck with some inertia in the platter I'm thinking
it may be
quite possible to get away with the following functional but odd
replacement.
Small diameter rubber or silicone cordage is quite easily available, idea is
to
plat/plait it 3 or 3 pairs at a time into a "flat" belt. But does anyone
know if its possible to back-splice platting to form a ring ?, any knots can
be on the outside safely.
I know from cutting down lorry inner tube rubber to make such belts, which
leave a rippled surface from pulling the rubber through a bean-slicer type
razor arrangement, but that does not seem to lead to wow/flutter on the
playing of records so perhaps platting would work also.
I comparison blind-tested one with a HiFi nut one time.

While at it - how do those ballister , bulbous drive pulleys for flat belts
work?
I know they always centre to the bulgiest bit but intuitively I would have
thought
they would slide down to a smaller diameter where the back torque would be
less
as the "gearing" is less there. Intuitively a concave profile rather than
convex profile of
pulley would seem to lead centralising of a belt.

Turntable belts right up to 205mm diameter are readily available from
Charles Hyde

www.chsinteractive.co.uk

in the uk. They are also " sensibly " priced, so no need for your self
amputation ...

why don't you look on ebay or even buy an old deck at a jumble sale and
butcher the belt out of it. otherwise i'm sure specialist companies
like linn products or rega would be able to supply one to you, through
your nearest specialist hi fi shop...
