4-Track Stereophonic / Monophonic Tape Recorder (1968-71)
The compact, but incredibly powerful stereo music control center TC-630 consists of an amplifier utilizing quality Sony silicon transistors, a precision three head tape deck and high performance speaker systems.
Silicon transistors and selected power transistors assure lowest possible audio distortion and uniform gain characteristics throughout its operating ranges and also improve signal to noise ratio.
Four pairs of stereo inputs, phonograph, tuner, microphone and auxiliary, correspond to the settings of the source selector on the front panel. Line outputs and stereo headphone jacks are provided for versatility.
The tape transport mechanism is designed to provide flutter-free, stable tape drive either in vertical or horizontal operation. The symmetrically arranged slide volume levers and the precise VU meters will be convenient for record volume setting.
Other features are automatic sentinel shut off device, retractable pinch roller for easy tape threading, instantaneous comparison of source and tape, noise suppressor for undesirable high frequency noise, sound on sound and echo effect for the professional recording techniques.

The rubber parts are getting a bit old these days and the costs to remake them limit the value of these machines. The heads are standard metal and tend to wear - watch for excessive use. They will run like new with a relube and new idlers. Good solid unit.
