Did you ever read the data sheet of your love? The TL494 is great for many things, except audio amps. The only fact, a device amplifies oscillations does not make it a great audio amp.
Do you use spaghetti to drill holes in concrete? Just the same, may work, but other drills are better.
So maybe cook your spaghetti, eat them and later find a new love, that does not reject your advances.
