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.Detailed info is here: http://www.pmillett.com/HVRECT_MEC2.html This auction is for one PCB only, no parts or anything else is included.
