i have a 390s and what you have is not normal.
Mark Levinson 390S Inverting Polarity?
If any wonderful folks out there who owns a Levinson 390S could tell me if your unit inverts polarity upon start up (switching the unit ON from the back) I would appreciate it. My unit inverts polarity when I switch the unit on from behind and would like to know if this is normal. Thanks All!
