Guitar amp project
After making the Standalone Voltage Regulator I decided to see what else could be made on one of the single IC boards from RadioShack. About a year ago I built a mini-guitar amp using an LM386 audio amplifier and a small 8 ohm speaker from an old computer, you can see the post on geeksinside.com. Since the LM386 only needs a few capacitors and a resistor I wanted to see if it can be crammed on to one of the boards. After a bit of study the answer is yes! This week I soldered the unit together and mounted it an acrylic box you can find at craft stores. I plan on doing a write up like the regulator, with part numbers and part layout, however for now I have a gallery up showing the finished product.
Here is a short list of the parts I used, for the ambitious:
- RadioShack single IC PCB
- 100 uF electrolytic capacitor
- 0.1 ceramic capacitor
- 4.7 uF capacitor
- 10 uF capacitor
- 10 ohm resistor
- 8 ohm speaker
- 25 ohm potentiometer
- 9v battery and snap
- 1/4″ mono phono jack
- LED
Here are a few links to simple amps using the LM386. LittleGem Amp CigarBox Amp

sorry, could share with me your circuit?
I’m putting together an audio amplifier but the output takes a lot of noise and I need a circuit that works.
I need the schematic diagram of the circuit.
