GAIN: this amplifier has an inherent gain of 11dB to pin F. The gain can be increased by taking pin K to ground (pin J)
through an R and a C = the C assures gain is only increased for audio (not dc) and the R sets the AC gain
R=1K2 and C=100uF will increase gain to 16dB
R=110 and C=220uF will increase gain to 31dB
note that at higher gains distortion will increase somewhat
