Default 3-brush gen problems

The three brush generator on my '36 pickup recently stopped charging, it was rebuilt about 8-9,000 miles ago and has been controlled by a FunProjects voltage regulator (the one in a cutout case); this setup worked perfectly until now. The fan belt is properly adjusted. The 3rd brush was set to give about 1-2 amps charge when driving. I disconnected the B+ and armature wires from the regulator, connected them together and it shows about 10-12 amps charge (on the dashboard ammeter) when running above idle, so I'm guessing the generator is OK and the voltage reg is at fault. As best as I can tell, FunProjects is no longer in business and so I don't think a replacement would be available. I can go back to using a standard cutout but I'm wondering if there other options?
Thanks,
Adam
