Heard this for the first time last night. Jenny has an awesome voice. Lyrics are a little weird at times, but also humorous. Very enjoyable album!

Where do you guys and gals buy toroid transformers at a good price? I need a 300VA 25-0-25 center-tapped one.

I am thinking about making up a CMOY pcb to fit in an Altoids tin with 2 9v batteries. The thing that always frustrated me with building CMOYs in altoids was wiring the panel mount components, so I want to do a pcb with board mount components to avoid the tedious wiring job. Here is something...

I want to build a simple CMOY-like headphone amp with the AD8397 chip. But I want it to be optimized for my Grados. I want to make the gain=2. So in the following schematic, I need to make R3 = R4, because gain = (1 + R3/R4). But how do I choose the actual values for R3, R4, and the rest of the...

Just wanted to share a couple of good songs I heard on XM Unsigned on the way in to work this morning: Will Dailey - I have to get you off of my mind http://www.willdailey.com/ Lemon Drop Kick - Vacation http://myspace.com/lemondropkick

Has anyone used AD8397 in a simple CMoy-like amp yet? Seems like it could have the current to drive Grados well?

I'm using the RK097 switched 10K ohm pot from Tangent's store, what are optimal values for R1 & R2? What is optimal PIMETA gain for Grado phones, using the aforementioned pot? Also, looking for suggestions on a good balance between sound quality and battery life when using Grados. How are...

Can anyone point me to a retailer in/around Kansas City that sells Grado headphones? I'm looking for the SR-60. I emailed Grado but it's been a few days with no response. Thanks, -Jason

Anyone else going out at midnight to buy Halo 2? -Jason

I'm thinking about learning to play the guitar. I would love to play some blues, but love rock music as well. I'm guessing an electric would be the way to go for me, but I don't really have any idea. I plan on going down to Mass Street Music (don't know if any of you guys have heard of it, it's...

I took apart my Toshiba 3960 tonight and when taking "before" pictures, I noticed that 2 pairs of pins on the main Zoran Vaddis 6 chip (the biggest chip there) were soldered together. Here are the pics: What do you guys think? I have yet to turn it on. I'm about to go back downstairs...

I purchased one of the Elma attenuator kits from Chris. Was wondering if anyone has any tips on what the best way to get the resistors in there for soldering but still keeping everything looking nice and neat, and the remaining leads (after soldering) straight. TIA, -Jason

Laid out for use with a LaRocco diamond buffer. Is there any downside to this (besides making sure none of the pins are touching each other)? -Jason

Besides the Intersil buffers, what other parts does one leave out of a fresh PPA build if building for use with the LaRocco buffer? LaRocco's page says to leave out the C2 caps, are those the only other parts besides the buffers to omit? -Jason

It's unclear from the schematic. I am using 2 9v batteries and creating virtual ground from the midpoint between them. Do I tie input ground, output ground, and virtual ground all together? That's what I've been doing, but I get hum in the headphones. DC offset isn't *too* high, 17mV/28mV...

I would appreciate some comments on a PPA/Grado SR-225 combo. I have the Grado's on the way, but don't want to dismiss them without hearing them with a good amp first, as from everything I've read, they need loads of current. I have a PPA sitting around that I don't use currently, just wondering...

Hi all, Just got an iPod 40gb 4th gen unit and extremely pleased with the portability. I can't imagine going back to carrying CDs around with me all the time. I currently use Senn HD280Pro at home, which I love, but they're not that portable, they make me look like a goof, and I hate carrying...

Sitting here looking at the stock Senn HD280 coiled cord and wondering how it was made. Do they take the fully made cable then coil it or do they coil the wire first before applying the insulation? The surface of the cable on the inside of the coil is flat, while the uncoiled part is completely...

Tangent's guide says around 1mA for biasing op-amps into Class A, but indicates that the required bias can vary quite a bit depending on the application. My application is: PPA, OPA627BP G, OPA637BP L/R, 4x Intersil buffers per channel, driving either Senn HD497 (32 ohm) or Senn HD280 (64...

Does anyone have some good suggestions of sites to go to for forums on car audio? I have a '97 Mustang Cobra with the stock Bose midrange & tweeter speakers. They are so very HARSH throughout their entire range that it's unbearable to listen to for more than a few minutes at a volume anything...

Here's some **** of my 2nd PPA. It's the PopPA Muse - PopPA (for "PPA"), Muse, cause it uses Nichicon Muse caps. The stats: OPAG - Burr Brown OPA627BP OPAL/R - Burr Brown OPA637BP C1 - 8x 330uF 25V Nichicon Muse KZ C2,C3,C5 - not installed yet C4 - 6x 100uF 25V Nichicon Muse FG...

...Stacy's mom has got it going on. -Jason

Just got some Senn HD497s yesterday and the cables plug into the earpieces with std. 1/8" mono plugs. Only problem I see is the plug housing, finding one small enough to fit into the earpiece jacks. Has anyone done this before and found a suitable 1/8" plug? -Jason

I know this is a dumb question but I don't know the answer. Measuring from the virtual ground (I use one of the empty ground plane holes for the Alps Blue pot - I used the Pana ECJ pot) to the OL gives me 11mV, and to OR gives <1mV. The docs on Tangent's site say to measure from vground to all...
