where could I get an armboard custom made?
the armboards from the manufacturer, for a Thorens TD-850, have a vta-adjustment collar which makes them suboptimal for my Origin Live arm. The arm is ostensibly a Rega-type arm, but it has an integral vta adjustor that makes it not quite right with the factory armboard, hence the need to have one made. Any help would be appreciated.
