These are two PCBs of a very low noise PSU board based on LT1963A.
LT1963A is one of the few low noise and high current LDOs that is proven to have excellent performance for audio application.
The board can be used as either for filament , DAC circuit or any linear circuit. For current higher than continuous current of 300mA, heatsink has to be added at the back.
The listing is for two pieces of boards.
The assembled board pictures are for reference. The listing is for two pieces of bare boards.
Supply voltage : AC3V to AC14V
PCB thickness : 1.6mm
Copper thickness : 70um ( 4 times standard PCB copper thickness !)
PCB dimension : 80mm x 27mm
