[HomeBrew] Power amp for LM324

[Loren Moline WA7SKT]

Hello,

I have a LM324 amplifier which has a 0 to 30VDC output. The chip is only capable of like 15ma output. I would like to drive a circuit that will put out 100ma with the same 0 to 30 volts. The LM324 amp I am using is a X3 amplifier that converts 0 to 10 to 0 to 30 volts.

Does anyone have ideas for a simple DC power amp? Thanks!
