I'm sure most everyone here is familiar with the Pass A40 (40 watt class A audio amplifier) DIY project from Nelson Pass. (I've tried to upload a screen shot of the schematic but this forum won't let me do that. So here's the link to the article: https://www.passdiy.com/gallery/amplifiers/the-pass-a-40-power-amplifier). In the article Mr. Pass says that capacitor C4 frequency compensates the amplifier using a feedforward technique. My question then is, could one change the high-end rolloff to, say, 80 Hz by simply altering the value of C4 (to use this project as a subwoofer power amp)?
