Just received my '77 Series 1 electronics harness back that was repaired by Ron W. New stereo jack, ribbon cable re-soldered, and preamp card refurb/service tweak with an FET replaced. My bass sounds even better, though it sounded great already. I had know idea that changing that treble pickup FET was needed, and wasn't ordered, but it was a good catch and decision by Ron. The presence of my bass has been noticeably increased--it's like a brand new fresh Alembic again, and that is a --great-- sound. Alembic simply doesn't do "ok", they go beyond the level and service of most makers.
