All of the guides I find are a year or more old.

Yes, but the cmoy hasn't changed for a number of years. Tangent's guide is considered the most complete.

Thanks

Is the cmoy still recommended? This will be my first DIY headphone amp.

+1 But, here is a nice one put together recently http://www.head-fi.org/forums/f6/str...isited-460669/

Crossed posts, Yes the cmoy is still considered the best starting point.

If you find something in my guide that's no longer true, or where it doesn't cover something you thing it should, tell me about it. I won't promise to fix it immediately, but the guide got to where it is today through regular updates, most often sparked by DIYer comments.

Thanks Tangent. Your guide is very thorough. I plan on starting the build next weekend.

Can someone recommend a best-bang-for-the-buck solder iron to use in making a cmoy amp? I own a solder gun and a solder iron, both are to big for circuit board soldering.

Thanks

If this is just a starter project.. as in you plan on moving up the chain to harder projects..,
I would recommend you spend about $100 on various tools that you'll need eventually anyways.

Flush Cutters
Wire Stripper
Multimeter
soldering iron- I recommend a hakko 936 clone by Aoyue.
Helping Hands

FYI, I don't recommend cheaping out on any of these components except for the multimeter. I cheaped out, and after less than a year, I am looking at replacing all of my components less the multimeter and the soldering iron.

and then you need to buy:
solder
flux pen
hookup wire


Yeah, it ends up being expensive in the end >_>

Thanks for the reply. I have some of those tools already, multimeter, wire stripper, and helping hands.

What is the flush cutters used for? It looks similar to some wire cutters that I have. Is there a decent solder iron in the $50 price range?

A flush wire cutter will allow you to trim component leads close to the board easily.

I like the Hakko 936, but I was happy with the Weller SP23L for a while until I got this. If I had to do it again though, I'd go straight for the 936.

SOLDER STATION TEMPERATURE CONTROLLED-MPJA, Inc.

thats what I have and it's just about in your price range.

There are other places that sell the same station as well, so you may wanna shop around. they are all made by Aoyue.

On the list of components, you have "Optional" listed also. Do you have a guide that shows how to install these optional components?

The same guide covers all of the optional parts. Power switch, pot, DC jack, output resistor...it's all there.

It sounds like you're standing by the pool trying to talk yourself into jumping in. How do we kick you through the web?

If you're nervous the first time around, stick with the default config that tangent has listed, but certainly don't be afraid to play around with some of this stuff. The cmoy is inexpensive and resilient enough that a little bit of messing around isn't going to result in an utter disaster (providing you stick within the given parameters on tangent's site)

That said, if you want a first time success for the morale boost, default config.
