Thanks, this will help a lot !
I'll have to wait until the unit arrives next week, but if it is a 100vac unit made for Japan only, there may be a power transformer issue. So 10S indicates 100vac primary and 12S is for 120vac ? Any chance of a transformer replacement to make this unit USA 120 vac compatible ?
I have a set of Stax SRA-10S headphones coming into my shop for repair next week. Does anyone have a schematic or service info ? Thanks, Charlie Brewer Tech Services Nashville, TN
