General layout

 

A view with cover removed 

Benefits:

  • A push-pull output stage;
  • Built-in smooth controls over gain and gain slope, molded case
  • An interstage attenuator and corrector for an active or passive feedback channel (switchable);
  • An input attenuator for an active feedback channel;
  • Test points:

                at the input - bi-directional

                at the output- directional
