The speed should not drift and the setting should not be changed each time you turn on the unit. When I bother to check the speed, it is usually unchanged. You should contact Basis, they are usually quite helpful.
Basis Syncro-Wave Power Supply
Any Basis owners out there? I inherited a Basis Debut Diamond Signature with the Syncro-Wave power supply. I have found that once I have dialed in the speed with my strobe disc, after a few days I check it again and the speed is a little slow. I dial it again, check again in a few days it’s a little slow. Does the power supply have memory system? I don’t have the manual so I don’t know if there is a way to save the setting.
Any info would be appreciated.
Thanks!
