Glad you were able to get the SL66 repaired. I love the system, and have been using it since 1973.
I have two complete systems, and sent them (body only) to Jurgen before he returned to Germany from Southern California a couple of years ago. He did a wonderful job with quick turnaround. I was not having any real problems, just a tune up.
I highly recommend him if you can live with the shipping time.
Jurgen was Brett Weston's repairman for his SL66 system, by the way.
