A386 Amp

This is a small amp similar to the "Smokey" amp and others from www.runoffgroove.com. Use the link to the site to see the schematic. This is a relatively simple effect to build. We built ours a long time ago in a “ribbed” Small Bear 125B enclosure that is no longer available. We also did a “funky” installation of the LED with hot glue. It looks nice from the outside, but if it ever goes out, it will be more difficult to replace. We used a Mouser 534-080 to hold the battery in place. We wired the on/off switching to a stereo input jack as is done in almost all the other projects on the site. The layout diagram has a toggle switch on/off like a real amp. You can wire it either way or with both as in the wiring diagram. If you want just the toggle on/off switch, you can use a mono input jack and wire the black battery snap lead to any ground point. If you want just the input jack on/off, then run the red wire from the “9v” pad on the PCB directly to the DC Jack. Use the project documents provided, starting with the General Build Instructions. There should be no other instructions need to make this simple little amp. Here's an inside view of the unit I built to give you some general ideas if needed. This is a nice little amp to have around the studio or bedroom. Have fun, comments and questions are welcome and can be sent to [email protected]
