Scott Stereomaster 636S

1 9 7 0 1970
1 9 7 4 1974

From just before the time of the first change of owner (1973) and thirteen years before the final vanishing under the Emerson ownership which is still on today.

Still with Daniel von Recklinghausen, too, before he went over to KLH but already with the SYMA International distribution / manufacturing / modding system in most of Europe which is probably what catalyzed the first change of ownership and put it in... Europe.

Scott probably got dead dry after all the resources spent on digital FM reception as put into the 1970 Stereomaster 433S and the well-remembered T33S tuner, both engineered by Klaus Peter.

Far from those high-endish and costly sci-fi units, the Stereomaster 636S is a powerful receiver with very nicely designed looks mixing light aluminium anodization in dark fashion (front, top and inner sides) and a wood enclosure for the back top and outer sides - quite not as effective as the Stereomaster 637S but attractive nevertheless.

FET Baxendall and concentric L/R tone controls, continuously variable loudness, "Perfectune" system, FET-charged 4-gang front end tuner section, IC-based MPX filter and regulated power-supplies.

And a large backlit dial which goes dark when the tuner section isn't used.
