Amplion Battery Eliminator DB3

amplion-corvetteThe early battery operated valve radios such as Ever Ready and Vidor are collectable, but the batteries are no longer available. I was going to build a power supply with 90 and 1.4 Volt outputs for testing these battery sets but I was lucky enough to come across this Amplion Corvette. The LT voltage was correct at 1.4 Volts but I’ve lowered it to 1.36 Volts to prolong the life of the valve heaters. I’d rather under run the heaters on valves which may well be over fifty years old. The Amplion M2V similar to the DB3 but with meter.
