On list is two pieces of high current DC regulator boards, using LM317K ( TO-3 package of LM317), or LM338K. Naim used two pieces of such regulator in their famous linear power supply hicap 1C.
The values printed on the board allows a steady +24V to be output.
Users can change the resistor divider values for other fixed DC values.
Supply voltage : AC 6V to 24V
Board Dimension : 54mm x 92mm
Board Thickness : 1.6mm
Copper thickness : 70um ( 4 times standard copper thickness)
