If you're not already set on having a female jack and a swappable cord, consider just chopping a USB cable, routing it though a rubber grommet, and soldering it into the board. Much easier to drill one hole of a known size than muck around with glue and filing an odd shaped opening into the...

Here are photos of the arrangement I used, and described earlier.

Thanks for providing such a great kit Guzzler! Here is a photo of one of my completed kits, all cased up. If you are using USB power, I highly recommend this enclosure; it machined cleanly (two holes), it seems bomb-proof, and it looks good (to me at least). It cost me about $5. The enclosure...

It is possible to fit two 9V batteries along with a MINT amp into an Altoids tin with the pot sticking out the end. It is indeed an "L" configuration. I don't have the amp I built this way with me, but here is as best I can remember/describe it: Halve the boards. "Mount" the amp board at a...

Just thought I'd chime in and express my interest in this project. If there are any of the previous versions of the kit available, I'd like to purchase one or two, and I'd also like to be a tester for the new version. Since you seem to be reconsidering the form factor for the next revision...

To get bit perfect output from iTunes application on a mac, 1. Turn off the equalizer, sound check, and cross fade. 2. Set the iTunes application volume slider to the maximum. I don't have the equipment to test it yet, but I suspect you will be able to get bit perfect output by using Jack...

Hello- I recently built two MINT amps. One is encased, other is just wired together. However, I'm having a weird problem where some sort of noise/distortion is being added to the signal at very specific volume levels. The noise, but doesn't sound periodic, and is certainly not a specific...
