Hi Paul
I purchased some replacement SB101 drive belts kits from a USA supplier a
year or two back at a very reasonable price. Each kit contains two rings of
2 inches ID and one ring of 2.5 inches ID. In all cases the ring material
has a circular cross section of approximately 1/8th inch diameter.
I have successfully used drive cord instead of the rubber rings but with a
tensioning spring inside one of each pair of drums to reduce the strain on
the capacitors. This requires more than one turn of cord around each drum.
