As many of you know Greg passed away a number of years ago. I had a chance to work with Greg both when I was employed by SSL and then 30 years later working on both BA-660 improvements and the Waveulator/WMD. Greg shared with me some work-in-progress schematics of the BA-660 which may assist those owners with repairs. Since the BA-660 was a continuous work-in-progress it may not apply to all the units he made.
