my UM1 cable caught on something the other day while the phones were connected to my ipod and wrapped around my neck. disastrously, the headphone wires ripped right out of the Y-split. i'm planning on re-soldering and heat shrinking the Y-split to repair the headphones, but i don't know which...

thanks for the replies. i'd been thinking that perhaps one of the 41hz amps would be a good fit. i have one of their amp10 kits sitting around waiting to be built, so maybe i'll give one of the more powerful ones a go once i finish the amp10. class D and class "T" (this is what Tripath calls its...

this isn't strictly HEAD-fi, but i'm wondering if anyone can recommend a DIY power amp that's suitable for use with a subwoofer (actually, it will be used with an enclosure that contains TWO 12" woofers, 4R impedance). i realize this is quite a tough load to drive well, but if anyone's dealt...

the best advice i can give you if you need to reflow and/or desolder joints is to get some flux paste. this is readily available at rat shack (here's a direct link), and although i haven't used their flux paste, i would imagine it'll work fine. all you need to do is apply a small amount of paste...

jambo, i might be interested in a kit as well, pending the final details. add me to the list, please!

lemme guess... amp10b? if so, i had the same issue when sourcing parts for my amp10. i ended up getting a sink intended for a DC/DC converter, from Mouser (P/N: 567-547-24AB). like you suggest, i was planning on drilling holes in the appropriate spots. since i haven't yet built my amp10, i...

^^ yep. (and in much more detail than i would have been able to give.) i ran into an example of this the other day - the larger, L-shaped piece within the LED's head was attached to the longer lead. as error401 suggests, and as it sounds like was the case for you, the lead length was a better...

just to throw my opinion in regarding 936-12 tips, i too think that the stock tip works pretty well for most SMD stuff. i also bought a very fine conical tip when i bought my 936-12, but i like the chisel tip so much better that the conical never even gets used. it just doesn't have the surface...

i haven't used the OPA2228P/A, but it sounds like it might be a bit more ornery than the old standbys, the OPA2132 and 2227. why not start with an op-amp that's easy to work with, then tweak your circuit later if you want to? nothing will be more frustrating than to have to do a bunch of...

forum members Zigis and Joshatdot have had their own PCB layouts professionally printed, and i know that Zigis was selling kits a little while ago. don't remember whether or not Joshatdot was selling complete kits, or just PCBs.

dumbears: jeff rossel (jeffrossel@glassjaraudio.com, Glass Jar Audio) sells Alien DAC kits and bare PCBs as well. he's a nice guy and a pleasure to deal with. shoot him an e-mail, and he'll send back an Alien DAC order form (an Excel spreadsheet) on which you can specify the components you want...

i've only built a single line-out adapter using fordgtlover's directions, but it worked quite well for me using the A/E connector type. it sounds like you've had some different experiences from me in terms of the connector's resilience and robustness, but all i did to avoid bridging (my...

if you're actually plugging a SPEAKER (rather than headphones) directly into the output of the Alien, that's bad news in the first place. the Alien is definitely not designed to see an input impedance of <1000 ohms at the least. even most headphones are pushing the current output capabilities of...

cetoole and tomb: i haven't grounded the pot yet. i know that the buzzing sound i hear when i touch the pot's shaft is from lack of grounding, but didn't realize that the scratchiness might be caused by the same thing. i'll install the ground wire and see if it goes away. EDIT: ok, minimal DC...

colin: i hear scratchiness only when i turn the shaft of the pot. i wasn't terribly specific about this in my initial post. is this still a symptom that would be consistent with DC on the input? i've only used an iPod as the source thus far, and i've measured very little DC on its output in the...

slowpogo: thanks. i think i have most or all of those parts lying around. i'll also have the pcb in the bottom slot (Jeff's kit with the big tall KZs and 1.5" sinks), so what you've described will work perfectly. much appreciated. tom: thanks for the explanations. i haven't logged any serious...

just thought i'd let everyone know that, after a misdiagnosed non-problem, my MAX is indeed alive and sounding excellent! everything's up and running, DBs biased to 100mV... just needs to be cased up. i do have a couple of questions, though - perhaps someone can answer them for me. first...
