Sears Professional Series Tuner (TR 6658) and Amplifier (AM 4658)
Although these units were sold by Sears , they appear to be made by Sansui as they are very similar to the TU-7700 and the SU-7700 models.
I have been trying to obtain manuals for the Sears models to no avail.
Any help would be appreciated.
PS.. I have been told that they sound just like the Sansui models they emulate
