    Found a really old Nelson Class A amplifier that has some protection against short circuit and a nice 0-500khz response. However it uses some really old parts from the 70s. I can't seem to get the ones I found as replacements to work in simulation. Is there any easy amps you guys know for about 20 watts covering that range?

    A class-A amplifier makes A LOT of heat all the time, even when it is not playing sounds.
    500kHz is a radio wave that is far higher than sound or ultrasonic waves.
    20W is not loud unless it plays continuously at full blast close to you.

    Awesome, thank you. I need to simulate to get it in my head as I think I'm pretty new.
