Take a look here for more efficient rectifiers

So...nobody knows if the correct looking updated rectifiers are available or can still be found for a CB77? I don't mind using a generic style one, however I would prefer to mount one that looks like the original orange finned style.

I have a RetroBikes one on my SuperHawk and it seems to work fine. Their website is www.olypen.com/retro, and their phone # is (360) 452-9043, Terry and Carole Kahler. They are in Washington State (Pacific Time Zone), so don't wake them up!

Another possibility to boost charging output is to find an earlier rotor without the (L) stamped on it. With the rectifier, older rotor, NOS stator and PowerSonic gel battery I'm pulling 13 volts with the lights on.
