SCOTT 631 Owner's manual

  • Hello! I've analyzed the service manual for the Scott 631 Receiver. This document includes specifications for the tuner, pre-amplifier, and power amplifier, along with detailed audio testing and alignment procedures. I am ready to answer any questions you might have about this device detailed in this manual.
  • What is the usable sensitivity of the FM tuner?
    What is the rated voltage output to a tape recorder?
    What is the frequency response in flat position?
