Hi all,
I am new to this site, if I do something wrong please let me know.
I just purchased a Nakamichi, OMS-2. Does anyone have a users manual for this unit?
Thanks,
Walt

It sounds very much like simple cold solder joints, which happen mainly on the power supply regulator board that is mounted to the back end of the unit behind the transport mechanism. Usually, one of the heatsink-mounted regulator devices will be the culprit, with cracked solder joints from heat expansion/contraction.
