I'm trying to get the "Sound 2 Light" circuit to work as a gate for my Anderton Ring Modulator build, but the LED stays on whether the input of the op amp is connected or not. I'm using a LM386n-3 instead of the LM386n-1 that's noted here:
Could that be the problem? Also gets VERY hot.
Can't believe I'm muffing up such a simple circuit!
