78 rpm era crystal carts are a restoration problem for sure, unless you can get it rebuilt. The crystal material goes bad from heat or humidity. Most 78 rpm era phonographs and changers track too heavy to use a more modern cartridge, and would need to be modified to lighten the tracking to go that route. The VM website should have rubber motor mounts that fit most units.
