So I'm integrating the SpeakJet into my next project, and using the LM386 to try to boost the speakers. Unfortunately, the package didn't include any circuit (or information whatsoever, really) and Radio Shack has discontinued their databooks. So I went to the go-to info tool, THE GOOGLE! I've seen this circuit all over the place:
A few questions about this circuit:
1. Is the .05uf cap and 10 resistor recessary if it's just going to ground?
