Like the TCI units, they're just all getting old and breaking down.
I don't have the link handy but a few members have had very good results with a fairly cheap regulator from O'Reilly auto parts. If I recall it's a semi-generic truck regulator. Should be available where you are.
There are a couple of threads on it.
Just about any regulator from a vehicle with an excited field coil should be able to be converted to work. There's an aftermarket ducati reg that I'm planning to buy once I get my '82 going.
