ELECTRA: Modular Powered Circuits - MPC11 Frognose Amp

Onto the Frognose - weird name right?  It's based on the LM386 IC, which is an audio amplifier capable of driving a small 8-ohm speaker.

In the configuration below, it's capable of 20x gain, so it's a pretty decent booster.

If you aren't familiar with the LM386, two of them are used in the Earthquaker Devices Acapulco Gold, and one is used in the D*A*M Sonic Titan with a JFET boost in front.  So if you put the Electra Power Overdrive in front of this, and added an extra cap to the LM386 you would have something resembling the Sonic Titan, or my version of this, the Kool Thing Distortion.  Not bad....  


FROGNOSE MPC11 - SCHEMATIC

Schematic was drawn by Steve - thanks Steve, hope you don't mind me posting it here.

As you can see, the Frognose is an almost part-for-part copy of the implementation provided by the manufacturer of the LM386.
