Welcome to Pass DIY! This is where you’ll find articles, information, files, and more to support projects from Pass DIY. Check in for news, micro-articles, and more.

All of Nelson and Mike’s articles are here along with files apps like the simulator for Nelson’s DIY Crossover. We’ll be adding new stuff as well as making the archive even more complete with classic schematics, historical info, and a few never before seen artifacts from the vault.

Thanks for being a Fearless Amplifier Builder!
