This is a blank PCB for construction of a DC power supply for a tube amp. It can generate 3 voltages: A high voltage B+, a lower voltage of 1/2 B+ (typically used for a screen supply or driver supply), and a third isolated voltage typically used as a negative supply.
It uses Tentlabs MEC (Mini Electronic Choke) in place of regular filter inductors, saving a lot of space and weight. The MEC can support currents between 50mA and 200mA depending on which module you use and the size of the filter capacitors you use.
