I bought an AR xa that appeared to be in good shape knowing I’d have to put some work in it. Everything about it has been some kind of issue but what I need help with is the motor/pulley configuration. The pulley is small, almost looks like the starter pulley from the 2 motor versions but I don’t think that’s the case. I obtained a regular xa 2-speed pulley but the hole is way too big for the shaft. With the belt and current pulley I can get the platter to spin but it’s slow, about 30 rpm. Is this a model that existed or a Frankenstein turntable I got ripped off on? Please help
