You could build a power supply. For the B voltage a small 12 volt lead gel cell and a pure sine wave power inverter 100 watts and the design listed above on Phils site. The A voltage same 12 volt battery and one of these your choice.   https://www.alldatasheet.com/datasheet-p...LM138.html    or https://www.alldatasheet.com/datasheet-p...M338T.html   or https://www.alldatasheet.com/datasheet-p...LM350.html     Have fun. David
