Just a little cMoy, cased in a cheap fake Tupperware that was the smallest case I could find at the dollar store. I feel kinda ashamed posting pictures of it next to all the pretty stuff here, but hey, es mi amplifier primero.
Unwilling to pass up a deal and liking the idea of handmade gifts, I bought parts for five cMoys based on Tangent's $20 amp list, going with 470uf input caps 'cos they were about the same price. I ended up wiring on an existing 6' headphone cable (cut down to about 4') instead of buying a mini-mini cable. The Tupperware works nicely here; you can wrap the extra cable around the seal (see first pic) and tuck it behind the flap that pokes down (see second pic.)
This thing *rocks*. I think a lawyer helped set the volume levels on my Dell DJ MP3 player. All the instruments are well-defined, but the OPA2132PA is pretty gentle to the lo[u]ssy MP3 compression. No volume pot or switch, power switch stolen off old broken electronics.
Hello,
@ days ago i built my first headphone amplifier (cMoy) which contains Alps RK097 pot and OPA2134 op-amp, powered by double 9V batteries. Built with help of tangentsoft cmoy tutorial. Sorry for ugly photos, but i can't make any better. Enjoy:
All of your links point to the same picture! The link displayed says one thing, but the url for them all goes to 1.jpg. Just thought you'd like to know.
So a little background - I had had my Koss/RadioShack PRO 35's for about 6 years - used them for bus rides to track meets, working out, general listening, etc. (kinda abused'em, I know), and finally the headband broke and my first "good" pair and favorite pair of headphones were broke/not usable. So, my girlfriend bought me the HD-590's for Christmas, which lead my to all of this expensive goodness called head-fi. I was rumaging through some stuff and came across the ol' 35's, and decided that it was their time to be reborn. I had seen a decent amount of DIY stuff through pics and what not, and I have a pair of the KSC75's, and seeing as how the actual '35 phones worked, just not the head band, I resolved to figure something out so that they could be used again. So, I set at making some ear clips. It probably took about 2 hours to do and began with me cleaning up the titanium drivers with a q-tip (gently mind you), then removing the little dents that I made in the driver, then I put them back in their house, and had at it with a white shirt hanger (these are generally thinner and more flexible than the average clothes hanger). After some trial and error on the shape of the clips I ended up with something study and not too uncomfortable, and so made one for each side and put some black heat shrink on it to make it look a bit better.
So far so good, I just have to get new foam for them because it was disintegrated form sweat and age. Hope you enjoy, and thanks for the ideas all!!

Oh dude, those are some seriously fugly phones! Gotta hand it to you, if they sound good, do it... just not in public But then again, you'd probably get similar reactions if you wear the wood or aluminum grados outside.
