2、trol Transformer Isolated 50% Speed Control Capable of powering synchronous motor audio tape drives, the Model 250A provides a simple and convenient means of switching between synchronous and variable speed operation. The power unit contains a stable voltage controlled oscillator which drives a rugg

3、ed transformer isolated power amplifi er. A solid state switch transfers the amplifi er input to the power line for synchronous operation in order to permit instantaneous mode change. Sine wave output of the Model 250A reduces bearing rattle and RF pickup usually associated with the more conventiona

4、l sauare wave capstan drivers. The remote control unit containing the variable speed control and the Sync/Variable switch may be mounted at any convenient location. The Power Unit is small enough to be mounted inside most tape machine cabinets, or may be rack mounted by means of an accessory adaptor
