Will, Still you haven't clearly mentioned what Model Turntable this is? All I see mentioned at this point, is the word "Jr"?
Is this a HW-19 Table? Or?
If it is a HW-19 Table, there may be diffculty getting much in the way of parts, or repair. VPI dropped support of this Table, being that it was made for a good 25 years, and while they have some parts still available, some things like Plinths, Armboards are most likely non-existent. Custom fabrication will be the only way, unless one could catch used parts here, but you may be in for a long wait.
If it is a more current model (Scout) then there should be no problem for any parts. Mark
