    What's difference between this power supply & the other similar type you build which says 0-28 volts?

    The heatsink I think is small and won't dissipate much heat when voltage drop across the Ic is large and more current of 1 Amp is drawn by load. Can we mount the Ic on metal cabinet to act as heatsink in this case ?

    ok I need help I have a AC/DC Unversal adapter TS506B.the switch broke and 2 springs came off and I don't where does the second spring goes so I decided to make a idea I will make a dc power supply 0 to 42 volts.the mah of TS506B is 1000mah it has voltage switch 1.5-3-4.5-6.7.5-12v I want to add the 42 volt to it.I have lots of VCR LCD screens,1 potentiometer and a 42v EPSON power Supply so how do make it to work.also my Mosfet P75NF75 on Amazon is coming this month on October supposly.I still have a QW-MS305D dc power Supply the problem was the mosfet was spoiled so I had to order the same new one.
