Battery Power Supply.


This power supply is a battery powered unit which enables powering a 4 valve Neutrodyne or similar from a 6v battery such as a Nicad or Gell cell.
It has an adjustable output and can be configured to suit the radio in question. All switchmode power supplies generate interference so the supply should be mounted in a metal box and if the same battery feeds the filaments a low resistance choke and bypass condenser should be placed in the filament line.
All components are easy to get except the 34063. If you have difficulty obtaining one email me for more info.
