Starting as a Kickstarter, this kit is fully live and on its own now. The Honey Amp features dedicated preamp and power amp circuitry as well as auxiliary input and headphone output jacks on-board. Taking up a scant 1.4″ x 3.5″ PCB footprint, this little guy can be installed in almost any enclosure. Full ground plane fill on the board helps limit extraneous noise and interference.
Pushing a 16 ohm load this amp will produce a maximum of 1.6 watts. On the other end of the spectrum, running a 4 ohm load on a 6v PSU will produce only 0.35 watts. I will say though, that 1/3w on 4 ohm is remarkably loud – running full volume your family will ask you to turn it down!
This board is designed from the ground up with tinkering in mind. There are spots to adjust the gain on the LM386, you can adjust the preamp to be a clean buffer instead of a gain stage, or you can simply start swapping filter capacitors to adjust the tonal range of the amp.
