National Semiconductor integrated regulator often uses LM3XX Series, and I saw a lot of sound systems used in the device power supply of the charging circuit etc in various systems. LM338K 1.2 with very little passive elements .. 5 amp power supply can be 32 volts.
A very simple circuit but stylish design a PCB can be useful Integrated given by the powers of 5 amps, but under certain conditions at high powers are going to use it first integrated the “K” series Metal large sheath which to use and good cooling suggest you do Setting the application can be made 1.2v.. 25v volts to 32 volts cancel the R2 resistance value of R3 potentiometer 5k 2.5k Use
