The diyAudio build guides
I'm a hard-core DIY builder. And by hard-core, I mean completely bonkers... :D :D :D

For approx. the last 4yr I've been making build guides (here at and elsewhere) for people interested in these projects. I've found that most interested parties can get one of these done with a bit of patience, guidance and a decent set of photos. So I've been doing that. It's a blast, and I've had the honor of taking to people (Email, phone, skype) all over the world about their projects and our hobby.

Most of these guides are Nelson Pass designs, but I will tell you that there is a reason his projects are so incredibly popular. Take a look -

Pass/Firstwatt F5 (My first big guide, and this is still the most popular project in DIY land) An illustrated guide to building an F5

The B1 preamp, this post got re-formatted and kinda screwed up, but still not bad. B1 preamp build thread

The incredible Pearl 2 phonostage - Building a Pearl 2

The F5Turbo amp (this one looks very clean, I'm quite happy with it) - F5Turbo Illustrated Build Guide

The legendary Aleph J amp, (what I've been listening to for quite some time) --

The Pass "Amp Camp Amp", this amplifier and guide is intended for the complete beginner, and so shows essentially everything -- ACA illustrated build guide

The Pass Burning Amp BA-3, this one has a video I really like in post #3 -- BA-3 Amplifier illustrated build guide

The front-end board from the BA-3 is a fantastic preamp, and currently in use in my system, here --

The Pass F4, this is amongst my most favorite guides -- A guide to building the Pass F4 amplifier.

The wonderful Amp Camp Amp v1.0 ACA illustrated build guide

The F6 amplifier F6 Illustrated Build Guide

And a few non-Pass projects;

The O2 headphone amplifier -- Building the O2 Headphone Amp

Hagerman Bugle 2 phonostage -

SL-1200 DC PSU -- SL-1200 DC Power Supply DIY

SL-1200 tonearm rewire -- Rewiring SL-1200 Tonearm

A guide to the universal chassis from the diyAudio store -

And the universal PSU guide - diyAudio Power Supply Circuit Board v3 illustrated build guide

Gawd, that's a lot of things when listed like that. :) I've never actually made a list as such. (And I haven't gotten any of my Valve project guides completed...)

My apologies, now that your eyes are bugged out from looking at all that, I suppose you would like to know a bit more about me... Here's everything you need to know about me in regards to DIY projects, a (literally) 5-min talk at Burning Amp Fest '13 --
