    Hi! I am looking into playing with some DIY audio. Wondering if we could make a community approved list of worthwhile projects for beginners - both in ease of completing and in expected quality of the finished product. Something like a proletarian DIY leaderboard.

    ***Beginner meaning an adult with some conceptual knowledge of physics and electronics and not excessively clumsy.

    *** Feel free to suggest other interesting projects

    Heh... personal bias. I would start with Headphone Cables, Interconnects, and Adapters. Once you have a couple of those done, I would move onto an amp. Since there are many good solid-state amps using tried and true but tiny surface-mount parts, I suggest a tube amp for that retro, hand-built look and feel. Also, I think a tube amp may be easier to learn from than solid-state amps with their black boxes of integrated circuits and microprocessors.

    Even though the parts are more costly, maybe add the Torpedo III as it doesn't seem that bad of a build.
    The Crack seems like a popular first build. The Projects and the T3 seem more professional in their finish. I am contemplating building a T3 over the summer... maybe.

    Just a niggle, but it is DIY. Do-it-yourself.
    Now that that is out of the way, I think cables are a nice starting point. Gets you used to using a multimeter and soldering iron on non-volatile components.
    Next, I'd recommend a CMOY so you can learn a little bit about simple audio circuits.
    I think the Bottlehead amps are great sounding, and their kits are impeccably put together - you can build a functional amplifier without having a clue about how it works for better or worse.
    I'd avoid anything that requires you to be too careful with heat or ESD issues at the start, so hybrid amps may not be the best.

    Have fun!

    The DIY Pete Millett Butte is pretty easy. It's a little more difficult if you use discrete voltage regulators, then more so with different caps, different pot, etc., given you can't use the stock enclosure at that point (or not likely). It has potential to sound pretty decent for a low price and while maybe will lose out on value with tweaks and part swaps, does let one play around with other parts easily.

    I voted for the Crack, as it was my first kit. Also check out Beezar's website - you could build a decent little Starving Student tube amp for around $150. Would be a fun place to start. They also have a couple of cool DAC's that look like decent builds. Then work your way up to the T3.

    AMB also has a bunch of fun projects once you are fully entrenched in the DIY sickness. The gamma 1.5 actually is quite the boss little portable, but might not make an ideal first project.

    I dont know if this is off topic, but my first projects weren't really audio projects. I wanted to get comfortable with soldering so I bought a couple of inexpensive Elenco begginer kits to get comfortable with soldering. If you dont have any experiecene with a soldering station, I would recommend this before any audio projects.

    Anything in particular we should look for when getting a soldering station to use for these sort of projects?

    This is the best thread to poke through for general advice: http://superbestaudiofriends.org/index.php?threads/solder-and-soldering-irons.659/

    Each product has their own help forums that might have specific advice to the project. The Bottlehead forums are crazy good resources with incredibly nice and patient people there to answer questions. Was invaluable to me when I built my amp.

    Awesome, thank you! I'm not sure I'm ready to jump into DIY yet but I'm glad to know the resources are available.

    I built the Torpedo III as my first project. Probably not the easiest go around, but everything was so well labeled I was pretty happy.

    I'm a novice myself. I can't speak to which of these kits are best, but I think there's another angle worth considering...when I started, I looked at kits too, but the problem with them is that they are very paint-by-numbers. And paint-by-numbers teaches you jack about painting. I like the CMOY route, you can do it paint by numbers style, but it's also a simple enough circuit for you to understand and do 'on your own'. You can understand what's doing what and why. The crux of it, of course, is the op-amp and figuring what it needs. There are so many variations you can try as well. I also think it's better NOT to use a PCB or Tangent's recommended board. It's really better to figure how the traces should go on your own.

    If I were to consider a paint-by-numbers style project, I'd rather consider what I want to end up with.

    OTOH, if you want to do yourself (DY), then none of these projects will really cut it. Actually the problem is that they may just cut it.

    Another "classic" is a weller wes51, but their QC on the "lower" products have been questionable it seems.

    The circuit specialist seems to be another rebrand of the many chinese clones (936 etc) on the market also. Maybe they put a little more QC into them, but the 936 clones are already pretty good for the price.

    I snagged an Oki PS-800 refurbed from Oki directly for 80 bucks almost two years ago, got a spare coil and two extra chisel tips as well. Supposed to be a pretty great iron, I actually haven't even opened it yet >.>

    Another interesting begginer project is the ELENCO FM/AM radio: much more components to solder to one's heart delight. Its cheap, relative to getting something like the Torpedo III and messing it up. The negative is that probably will end up in the trash after the giggles of making something that works wear out - its been a long time since I used a radio on a regular basis anyway.

    They have a dozen or more of these projects. The practice kit is really for someone who has zero soldering experience. I did like soldering something that either played the radio or has some actual use. More rewarding experience.

    So after doing some research on various DIY stuff, I've changed my mind on build projects. Cables and interconnects are still first, but I agree CMOY should be second. If you really want to learn by tinkering, I would buy 2 CMOYs and try to build them to produce as near identical sounds as possible. Then, tinker with one. That way, you can learn how measurements and sound change with different parts, and you have a reference CMOY to compare to for <$100.

    Cables, then CMOY, then through hole, then something with a little SMD. Looking at the projects, cable > CMOY > maybe the butte then you're probably ready for quite a bit more.

    I went straight for the Butte after doing a handful of RCA to BNC swaps. Have never done a cable or much soldering at all beyond that. The nice thing about the Butte is how straightforward it is. The guide Pete provides is just amazing for total noobs. He has the BOM ready, some custom parts (PCB and chassis), and the guide not only tells you how to solder but walks you through every single component and where to place them. Even tells you when to bust out the multimeter and exactly where to measure. Some of that stuff gets glossed over when experienced individuals try to write guides for noobs. Harder for them to put themselves in the noob's shoes.

    So, it's not so much that the project itself is the easiest, but the instructions are just so damn good that almost anyone with even basic soldering experience can do it. Plus the payoff is a pretty nice sounding SS amp for cheap.

    I will say, though, that the SMD components were difficult. They are optional, but I recommend them. There was a measurable decrease in the noise floor after I put them in and the sound became smoother.

    I also went through the trouble of using discrete voltage regulators. That required a crafty fit (i.e. bent pins, regs at 45 degree angle) to get them in the case AND with the heatsinks installed. I can't say how much they changed the sound over stock regs, as I never listened to the stock regs. (I used the Sparkos regs.)

    The main downside to the amp is the volume pot. It has very poor channel matching, and with the stock level of feedback (rather high gain), you basically have either low volume that's poorly matched or OMG OW MY EARS BUT AT LEAST CHANNELS ARE MATCHED...WHAT DID YOU SAY? At that point, the Butte essentially only works with hard-to-drive headphones.

    Anyone interested in the Butte build, I can send the info your way on what resistors to swap to change the feedback level. I have mine at very low gain right now, which means more feedback. I'd prefer a higher gain but have to compensate for the stock pot.

    If you go for a custom chassis, you could put in a much better pot, easily put in some discrete voltage regs, and use more fancy pants resistors and caps to tune the sound. The stock build is cheap for a reason but sounds good regardless with the right opamps. I think the DC coupling helps with body and weight, and the measurements are solid for anyone that's totally objective. The opamp choice he picked seems to work well too, though that can change based on one's tastes so long as they consider gain and stability.

    I'm considering doing a new build or rebuild. I want to swap out some caps and the pot, which will mean a different enclosure.

    since it's your first build, you can try an O2. If you screw it, you won't be so sorry.

    I'm curious at the BOM and difficulty of that Krell Klone but I can't really find too much information around the internet. From the few PDFs I found, it doesn't seem a whole lot harder than the CKIII.
