Acoustic Research Pulley

[Walking Thunder]

Greetings,

I recently bought an AR TT turntable. This is one of the early models, with two motors (a 600rpm motor and a starter motor) and a single-speed pulley. The pulley has a step for the starter belt below a 33 & 1/3rpm step for the main belt. Aside from the step for the starter belt, and only having one speed, it also differs from the later single-motor XA/XB pulleys in that the bore for the motor shaft is smaller, .078in as opposed to .125in.

I know that some of these two-motor models (the early XA labeled ones, I believe) came with pulleys that have a 45rpm step as well. I'm wondering, can anyone here advise me as to where I could find one of these pulleys?

To clarify: a pulley with three steps (starter, 33rpm, and 45rpm), and a .078in bore.

I already asked Dave at Vinyl Nirvana if he had any and he does not. Any help would be greatly appreciated. Thanks.
