  • Notes
  • Xtratone plus valve unit

    This is a device for quickly incorporating a further stage of LF amplification in an existing receiver. It takes the form of a small 3” cylinder, with 4 pins in the base to plug into the valve holder of the last valve of the set. Two valve holders are placed at the top of the unit and by inserting valves in these a further stage of resistance capacity coupling is added without altering the wiring of the set.
