@russ69 -- the Ohm people haven't repaired the original Ohm As & Fs for many years now. They had one fellow who knew how to do it but he retired 10, 15 or perhaps more years ago. These days Ohm will only replace the driver with one of their current models.
As others have noted, Dale Harder is the only person I know of that works with the original drivers, so the OP would want to discuss his situation with Dale if he is determined to rescue his drivers.
