STAX SRM-1/MK2. Electrolytic power supply capacitors just replaced with appropriate larger value, long life, high temp versions. Settings calibrated. Should be good for at least another decade. If not refreshed as this is, these are all now old enough that the original wet capacitors will be needing replacement.Its had the Pro Bias portion of the main board populated to expand its use for high bias Stax earphones. These came in a few versions with the same board that simply needs to be populated for what is preferred. This one has been updated to do both standard (6 pin) and Pro (5 pin) bias. Easily removeable tape with PRO added to show that socket with the center hole plugged to prevent standard bias 6 pin bias phones into the 5 pin pro socket. Wouldnt damage them unless played quite loud but all sound better with the correct bias. Very good overall and excellent condition for its age. See pics. Careful of foreign sourced units without the mutli voltage tap in the back. 100v units do not run to spec in North America.
