[Stax SRA-10S schematic]

Thanks, this will help a lot !

The SRA-10S and SRA-12S are identical so this applies:

If it indeed a SRA-10S then it is 100V only (that is the reason for the model distinction) so don't run it off 117V like that. 

 

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,
