Hello all...

I recently dug up an old JC Penney MCS 2230 integrated stereo, and I'd
like to get the turntable going again. (Despite the source, it's a
pretty nice stereo system...the radio tuner works well, it seems to have
about a 40Wx2 output power rating (which seems reasonable, having looked
at the internals), the cassette deck is a partial logic design with the
ability to skip ahead 1, 2 or 3 songs and the turntable itself is a
linear tracking type.)

Anyway, before I stored it, the turntable was in need of a new belt. I
set the belt aside and now it seems to be gone. I could have sworn that
I read about how to determine an unknown belt size in the FAQ, but I
could not find it just now. As best I remember, a string was used and
placed around all the components driven by the belt, after which a
measurement was taken.

A turntable belt has a lot of stretch to it.

Depends on the individual TT. I've seen belts made of rubberized fabric
that didn't stretch at all. My old Rek-O-Kut TT had a belt that would not
stretcch at all made of some woven vulcanized rubber stuff. Any TT with a
heavy platter like the Rek-O is likely to have a stiff belt. Some of the
el-cheepo tables with aluminum platter will likely have a more stretchy
belt but it's not etched in stone.
