Schematic with voltages for Stax SRM-323 MK2-Any available?

[djsb]

Hi,

This is my first post on the forum. I have a STax SRM-323MK2 driver unit and a pair of SR-303 headphones. I would like to do some checks on the voltage levels (AC and DC if possible). Is there any service information or a schematic diagram available for the SRM-323MK2? Thanks.
