I would like to amplify the output from a function generator. The freq range needs to be from DC to around 10k Hz. Signal may be triangle, ramp, sine wave, square wave or whatever. I want to drive motors and other stuff with the amplified output. Need up to 50 volts and 10 amps. Thinking op-amp and transistors or something like that. Any help on pointers on schematic etc would be appreciated.
You better to go ahead with class D power amplifier for high power application see the link below
**broken link removed**
It is rated 500W audio power actual power (RMS Power) will be less than 500W
