Received this e-mail yesterday: Attention All EHX Tube Customers Yesterday, Russia imposed a ban on the export of some 200 goods in response to the sanctions imposed on it over the current conflict in Ukraine. We have confirmed that the ban applies to our seven brands of Russian tubes...

I'll start with some pics! The Audio-Video Club Of Atlanta sponsored a headphone meet on Sunday, May 7, 2017 at the Dunwoody Driving Club. A fun time and great headphone listening was had by all!

The Audio-Video Club of Atlanta is proposing a headphone meet on Sunday, May 7, 2017 from 12 to 5 PM.  The proposed location is at the Dunwoody North Driving Club, north of Atlanta.  Detailed directions will be provided later in this post.   Local retailers and popular manufacturers will be...

Some of you have built a Torpedo, designed by Dsavitsk of ECP Audio.  The Torpedo has been around for awhile now and represents a true, output-transformer-coupled tube headphone amplifier.  What made the Torpedo unique is that except for a single volume pot ground wire and a PCB safety ground...

For awhile now, I became aware in an acute sense of how fickle a USB connection and power supply is from many PC's, especially a laptop - even one with an elaborate docking station, etc. The reason is that the pupDAC, designed by cobaltmute, seems to push the limit of what is possible with a...

The pupDAC is the newest DAC design from cobaltmute, the designer of the grubDAC and SkeletonDAC.  The pupDAC is a design primarily intended for the finest possible sound from a USB-only-powered DAC.  While DIY-friendly with a now forgiving layout, it is very compact and designed for the tiny...

While I'm still working on getting the kits and website ready, I thought I'd post a build thread for the Dsavitsk/Beezar Torpedo amp.   To review just a bit, the Torpedo is the latest iteration of Dsavitsk's parafeed designs known as the L'ess Pressivo. There are many links that chronicle...

In my spare time (what little I have of it), I like to watch old science fiction movies.  One that I watched a few weeks ago was the forerunner of the theme in the Terminator movies: "Colossus, the Forbin Project."  The story tells of a computer so large, so advanced, that it gains control of...

Cobaltmute's new GrubDAC was originally designed in conjunction with Joneeboi's new Carrie USB-powered portable amp.  However, it has all of the same uses as the BantamDAC - stand-alone, CableDAC, Millett MAX and MOSFET-MAX.  The PCB's have been shipping for awhile and we hope to have kits...

OK. You guys win. I thought this would be OK in the regular thread, but I'm seeing other posts about, "Why isn't there a step-by-step guide for beginner headphone amplifiers?" So, let's see if this works when I post it separately. EDIT: Be sure to check the Starving Student Millett Hybrid PCB...

Holy cow and shazam!! Just when I was getting a little bit down at all the work to ship out the MiniMAX cases, the FedEx man rings my doorbell this morning. He gives me a box. Inside is a Christmas present from my friends on Head-Fi!!?? Turns out that under the wrapping (my wife made me open...

(Posted in the Millett MAX thread, too.) For those of you waiting for John (navships) to get back to his shop on ebay and for those of you looking for some 22ga hookup wire - I got this message from him this morning: Quote: Hi, I just got in a lot of 22ga wire. I was hoping to get this...

Brand New Sennheiser PX100 earphone Black For MP3 CD MD - eBay (item 320246565252 end time May-03-08 10:55:00 PDT) Even with shipping, that's less than $23 - almost too good to believe. There are almost a dozen listed like that on the bay right now.

Yep - it's official on their website: LEDs - LSDiodes Optoelectronics. They're closing up shop. I think like some other DIY-er's, they've been my exclusive source for ultra-bright LEDs. So, I'm asking for help. Please tell us of your alternatives and your experiences, if you have them. I...

ATL Nov 10th Meet Much fun had by all! Many, many thanks to PiccoloNamek who hosted the event at the Holy Cross Anglican Church in Loganville. Pics:

After reading countless threads from searching, I've just about decided to make/braid my own SPC from Navships for a pair of HD580's. I love the effect that a Cardas cable has had, but switched it recently to a new pair of HD600's. The 600's sound great, but now the 580's sound a bit dull with...

Interest check on Steinchen's discrete buffers for the SOHA: http://headwize.com/ubb/showpage.php?fnum=5&tid=2362 Although not strictly analogous, this should be the SOHA version of the Millett DB's in terms of the ultimate sound quality option for the SOHA. There are several circuit...

TubeDepot in Memphis, Tennesse I'm in Memphis for the holidays, and in an area close to the TubeDepot's address. I had some time free from the relatives yesterday, and thought I'd try to find the place. After a few wrong turns, I found a small industrial/commercial warehousing area between...

Looking at Tangent's STEPS article, he lists slo-blo BUSS fuses in everything from 0.1A to 0.5A for the line side of the transformer. However, he doesn't discuss how these ratings are selected, and they don't have a one-to-one correspondence with the various STEPS VA rating selections. That's...

There have been several posts lately about trickle chargers for battery-powered amps, and how to design/build them. Here are some building photos of trickle chargers for a couple of PIMETA's. The chargers are based on the LM317, with 2x9V, powered with a linear regulated 24VDC 500ma walwart...

There was a thread awhile back when these phones first came out, but I haven't seen any since. Seems some people like their looks, some hate them. I like the looks, but not enough to buy them if the sq is not there.

The Millett guys claim OPA551PA may actually sound better than the BUF634, and works in the same socket if you jumper pins 2 and 6. Jumpering these pins do not affect the BUF634 if you plug them in, instead. They also state the OPA551P1 can't be stacked and doesn't need it. Would this option...
