Multi Elmac PS-500

AC power supply for the A54 Some pieces of vintage ham gear are not really unique, but are so rare as to almost never be seen.   The Multi Elmac PS-500 power supply is an example, it was sold as an AC power supply for the A54 and A54H transmitters in the mid-50s. There's nothing special about it - just a big transformer with 5 volt rectifier, 6.3 volt filament, and 500 volt secondaries.  Two nice chok...  READ MORE
