I have been building and maintaining PCs as a hobby for 25 years. I have avoided iPods because I do not like buying something and having the seller still have control over what I bought through DRM. However my daughter has an iPod and I need to re-install the OS on her PC (that has iTunes on...

This isn't exactly headphone related but it is audio related... I have a Carver C500 amp that recently stopped working. The main line fuse is blown and one of the secondary ps fuses has blown. I have minimal troubleshooting skills but I have learned a few things building various head amps...

My daughters' birthday is coming up and she wants an Ipod Nano. We are a 4 MP3 player family (none are Apple). Currently I store all of our ripped MP3s on one computer and share them across the network. Just plug in the USB cord and copy the MP3s to the player. Simple. I don't know too much...

Every once in a while I will d/l a Linux distro and install it on a spare pc just for the heck of it. I might spend some time getting peripherals to work. I poke around a bit and quickly lose interest. I recently tried Mandriva Linux 2006. I have tried several Mandrake versions in the past so I...

Last night I was listening to my chassisless (is that even a word) Dynahi ( http://www6.head-fi.org/forums/showp...&postcount=901 )while researching some chassis options when all of the sudden I see a puff of smoke rise from the power supply . I powered down immediately and did a quick...

Has anyone here ever dealt with Digital & Analogue Audio Logic ( http://www.digitalanaloguediy.com/ )? They have a chassis that would be perfect for my DynaHi. Ordering is via E-mail. I e-mailed some questions on 1/29 and immediately got an auto-response stating that he is out till 2/3 and will...

I recently ordered a transformer from Richard Sumner Techlology (www.sumr.com). It was shipped as promised on 1/10/06 via Canada Post Expedited Parcel. The tracking information says that it was accepted at the post office on the 10th and went to the sortation facility on the 11th. It is now the...

As I am getting ready to order parts for my PSU I notice that the reference pic of the board I was using http://home.earthlink.net/~dgardners...power-rev1.jpg does not match my board exactly. Mine only has one diode near the 338's, one diode disconnected by the 4700uF caps, a 10K varistor next...

Just got a bunch of DynaHi and DynaHi PSU parts from SFT. I ordered everything that SFT sold relating to the PSU (except the board which I already had). I hadn't even looked at the board or djgardner's BOM (http://www.djgardner.com/headphone/g...nahips/BOM.pdf. 1. I ordered some Holco H4, 10K...

I’m pretty close to making the decision to build a Dynahi. I plan to buy two pre-built amp modules with heatsinks from SFT. I will build a Gilmore PSU but will buy the heatsink from SFT. I realize that a Dynahi can be a challenge to build. I think I may have got around a few of the trickier...

I've got the upgrade bug again. I built a PPA with LaRocco's Dyno-Biased Buffer and modded my XCanV2. I really like both amps but as I say, I have the bug. I am thinking about building a Dynahi. After researching the process, I think I might buy a pair of amp modules from SFT and build a KG PSU...

Has anyone here bought anything from Surplus Sales of Nebraska? (http://www.surplussales.com/). I found out about them through a thread on DynaHi heatsinks. It is located in Omaha (which is where I currently live). My only source for electronic parts locally is Radio Shack 99.9% of my DIY...

Has anyone here used the new material option 'Perspex' in a fpd panel design? It comes in clear (to 4 mm max thickness) and red (to 3 mm max). There have been some nice looking acrylic panels made by fellow headfi'ers with access to milling equipment. Too bad you can't get thicker material as an...

I can kind of see the 4 in 42 but the rest just isn't there for me. In high school I considered joining the Air Force to get electronics training. I took the physical and in the eye exam I took a similar test and failed it. At that point they told me electronics training was probably out. Later...

I currently run my PPA w/ OPA637's L&R and 627 on G. I ordered some sample AD8065's but they only ship a max of two samples so I ordered the 3rd one. The samples came in two days but it's going to take a week or so for the 3rd one. Could I use the 2 8065's for L&R and use an OPA627 or 637 for G...

I just got some 24 guage silver plated copper wire w/ teflon insulation. I plan on rewiring my PPA internals. Basic question - Is this a proper guage to use?

I own all of the qatsi trilogy (Koyanisqatsi, Powaqatsi & Naqoyqatsi) DVDs and soundtracks but YoYo Ma's cello on Naqoyqatsi is my favorite especially the title track. I'm looking for something similar to the title track. Any suggestions?

Does anyone use ETY-4S/Ps with their home rig? Most of the threads that I read seem to talk about portable use for these. Do they stand up against full size phones? I just ordered a pair of 4S's and plan on using them portably but I'm curious how they will sound on my home rig compared to my...

I just wired my crossfeed board into my PPA. I'm hoping there's cotton deep in my ear canal because I can't hear any difference (Enabled, Bypassed, High, Low). I'm hoping I wired something wrong. Here's how I wired it: S1LL -> | [] [] | <- S1LR......When switch is up, S1HL & S1CL are...

This project has turned out better than I could have imagined. It still needs a little work. The crossfeed circuit is built but not wired. I will be installing Glassman's diamond buffers when the next batch is available. I might put in a glass or lexan top... possibly change the screws on the...

My OPA633 buffers in my PPA are running very hot (they will give you a blister if you touch them for more than a second or two). This topic has been covered elsewhere on this forum so I am not asking for a solution. What I am interested in is how this might affect the buffers themselves. I know...

I just completed a PPA with one OPA633 per channel. On first listen it sounds harsh and lacking in bass to me (also when I switch to HA3-5002s). I realize that it needs to burn in for a while so that may be normal. I am used to my XCanV2 tube amp. I have only listened for less than an hour...

I have a completed PPA using one OPA633KP per channel (I also have a set of HA3-5002s that I bought for troubleshooting purposes). I plan to populate the remaining buffer slots soon. For the remaining 633s it would cost $82 plus shipping. I think the Larocco Diamond Buffer set is around $100...

My first real audio diy project other than some audio tweaks (capacitor upgrades, etc) was to build a PPA. Yeah I suppose I should have started with a CMOY but I have decent soldering skills. Anyway, the build was fun until it didn't quite work right It is being diagnosed as we speak by someone...

Has anyone here had any experience in creating an HPGL file for Front Panel Designer? I use Autocad just about everyday at work so I think I can make the file this way. I tried making a plot file from a simple drawing but when I insert it all I get is a crosshair as a marker but no design. It...
