$30.00

Two working Eico power supplies or battery eliminators.  These are designed to be used on the workbench as 6 or 12 volt supplies for repairing automobile radios.  They use a unique variable transformer like a low voltage variac or Lionel transformer.  Variable voltage, but not a regulated supply.  On the 12v setting (10amp) output is adjustable from about 1 volt to 31 volts.  On the 6v setting (20amp) output is adjustable from about 1 volt to 15.8 volts.  The unit with the white posts has slightly lower output (Hi is up to 28v and Lo is up to 14.3v).
