Which regulator are you looking for? I have a new on off a 60 ampI am finding myself in need of a good regulator. I have the kind that looks like a Starburst. This will be my second replacement. The brushes looked good previously when I had it open and I blew everything out. It worked flawlessly until it quit altogether. Now its 24.3 on or off, it has voltage to the exciter. Last one was a ebay NOS. Not sure if China or not but it didn't last long.
If anyone knows a good economical source please let me know the name.
