I can do that. OK, billy will tell all this is true. I did offer to be part of billy's team if he does the ground work for the head-fest 2008 in chicago. I also agreed to bring an infinite amount of liquid nitrogen and a dipping dewar. People can cryo anything on the spot. For FREE!!!!! Requirements: someone with a pickup truck, van or other such vehicle preferably with a lift gate so that i can bring the dipping dewar, and as many 100 liter tanks of N2 that we will need. And a strong person. 100 liter tanks weigh about 325 lbs full. Make that 2 other people... Am I crazy or what?? We can start with billy's penis. Anyone have a tweezers and a magnifying glass

So now that things are slowing down a bit, i got this idea to build a massively huge BH. So i'm thinking 4 x 3cx400 should be absolutely perfect. Running at about 50 watts plate each. Designed for grounded grid from the start. Anyone have some with sockets and chimney. Current best price on the tubes i have found is $480 each. Can't find any new sockets, just old pulls. If anyone has any idea on glass tubes (as opposed to ceramic) that are triodes and NOT DHT, i'm willing to listen. Current production a definite benefit. No 811,813,8000... as they are all DHT.

But that is a right handed sky hook. Which is completely unacceptable

I forgot this one. All you really have to do to see how point to point is done is to look at some of the woo audio stuff. Absolutely each end of every single component is mounted to something. Then take a look again at pabi1's electrostatic amp. Notice any difference??

Yes a number of cold solder joints. Or shitty solder. Or both. say 20% of the connections. Those motor start caps are definitely surplus. They are absolutely fantastic caps, and to buy them new these days would be expensive. And likely the materials inside them are filled with carcinogens. Not likely to explode or leak as long as they are running under their max voltage. Botique parts, me, never most of my parts are way past that into the completely unobtainum list. Air mounting of components is only OK if you use left handed sky hooks. Peter is obviously using right handed sky hooks. Remember where justin is now. In ten years he will be making $40k a pair power amps, $50k powered subwoofers... $18k preamps... Hmmm where have i seen this before??

Actually jay's unit did look worse. wandering drill marks all over every single tube socket. HEY PETER, go to sears and buy a cheap drill press. Cold solder joints all over the place. Peter uses the best parts he can buy. At the army navy surplus store that is... Air mounting of components. Just like mikhail's early work. Actually worse. Diode bridges made out of smaller diodes in parallel, and alredy burning their way thru the perf board. I could go on and on, but jay should really either post the pictures he sent me, or allow me to link where they are stored I have pictures of his production power amplifiers. Every bit as bad. Speaking of the BH, i just got from justin the first KGBH-SE. Wait till you people see this thing. If i post pictures he will surely kill me He is selling it way to cheap!

If you all would see the pictures that i have seen on the inside of the thing and knew anything about vintage stuff, it would become completely apparent from the kind of wires coming out of the transformer that they came specifically from machine wound transformers made by STANCOR. Nothing else looks like that. There is also another teltale sign from the bottom that also specifically points to STANCOR. Peter needs to knock off the complete bullshit.

BULLSHIT on the hand wound part!

where i get my precious metals is my own business I'm not getting them where you might think And i'm certainly not paying the going price either.

OK, here you go http://gilmore.chem.northwestern.edu/metals.jpg upper left, my first casting job. Real shitty but i keep it around to remind me how bad my first couple were. upper right, 100 oz of .999 fine silver. Lower left 5 grams of rhodium. 83 grams of 24k for my stax portable. Then 31 grams of platinum and 50 grams of u238

I also have about 50 grams of depleted uranium 238. Sitting in the appropriate plastic bottle on my desk at home. (the radiation emitted is stopped by this particular kind of plastic). Since i don't know what i'm doing in this case i'll not try and cast the stuff. I've been told that machining the stuff after casting is almost impossible. I have a lot of .999 silver. Sooner or later i'm going to make a knob out of some of that. But it does tarnish very fast. One of these days i will have enough rhodium. But not any time soon Copper is way to easy.

That monstrosity from mikhail was coated in about 2 oz of gold. Absolutely the entire thing, knobs included. Can't get more gold than that unless you use my 24k volume knobs. But really gold is so last year. This year it has to be platinum. Another few months and i will have enough to make a 100 gram .950 platinum knob.

that is the seriously shrunk down version. The real thing costs a lot more. I would be happy to tell you the real cost, but as usual i don't have the faintest idea

pens?? Did someone say pens?? http://gilmore.chem.northwestern.edu/pens.jpg Including 2 vintage 14k solid gold cross pens (the fat boy and the one next to it) A sterling silver mont blanc, and 2 sterling silver watermans. Plus a whole bunch of 1940's vintage resin pens...

Board is 4.95 x 5.40 inches, 302 holes. I'll take 5 boards please...

The dynafet has that slightly sweet almost tube like sound that only fet outputs can have. But because of the drive circuit it has the balls of no other fet output amp i have listened to. If you want to buy one, you will have to find someone willing to build you one. And as usual there is a whole bunch of different ways to build this thing.

prototype works absolutely fantastic. Latest board layout at headwize.com in the thread. I have not had the time to verify that final layout completely yet. Sure would help if someone with much younger eyeballs would look at it and make sure it is correct before i spend $500 on boards.

the line outputs certainly go thru the tube and a pair of fet outputs so there will be a definite sound to those outputs. It is unclear from the schematic where the tape outputs are wired to http://gilmore.chem.northwestern.edu/melos.jpg

The $600 would be my price. You heathens would have to pay significantly more Its the reason god invented goy's. Someone has to pay retail...

Bet you all can't guess one of the things i'm going to do with this thing... http://gilmore.chem.northwestern.edu/bxrayn1.jpg http://gilmore.chem.northwestern.edu/bxrayn2.jpg http://gilmore.chem.northwestern.edu/bxrayn3.jpg http://gilmore.chem.northwestern.edu/bxrayn4.jpg 3 times the flux and 16 times the resolution. At this point i'm pretty sure i can take pictures right thru the outside case without ever taking the thing apart

The ground channel as used in the aria is very different from the ground channel used in all of the other 3 channel versions. It actually has -(L+R) as the signal as opposed to a buffered ground. Very different kind of thing. Think of it as an attempt to boost output voltage from a lower voltage power supply. A bridge amp of sorts. Of course if you do balanced all the way you don't need an active ground channel. Some believe that the ground channel shunts power to the other power supply rail instead of poluting ground. My opinion is that the 3rd channel just decreases the damping factor and really offers no other benefits. So 4 channels is the way to go. I've never seen a set of real headphones that cannot be wired for balanced. (iem's don't count)

I evlauated this exact circuit almost 4 years ago when i was trying to do a portable on a lower voltage power source. It just can't cut it. Especially for music where there is a lot of in phase mono present. (like a single female voice) The ground channel works even harder, and since it drive 2 loads at the same time, it work worse, not better.

Lets see, $5000 phono preamp, no painted over chips here Lets see $2900 apache balanced headphone amp, no painted over chips here either $900 HR2. nope, no painted over chips. XP7..... why only the sr71,hornet and tomahawk? Maybe ray was pulling a headphonia?? seems like you have to spend at least $500 to get honest product. I got this brand new apex2 xray coming in less than 2 weeks. 16 times the resolution of my old unit. You get me ray's permission and i'll post the metalization pictures...

no billy you are just plain fucked up. A high res Xray of the metalization layer complete with the manufacturer identification is all that is needed to identify a chip. And when ray says it ain't so he is just a fucking liar. pardon me, i have to go to my best friends funeral tomorrow. Not going to take shit from billy today.

With respect to the second quote, there was a lot there that i left unsaid. The people who know what i'm talking about obviously know what i'm getting at, and the people who don't are going to have a hard time figuring it out. That way the hammer is not so obvious. I have never had a problem with commercialization. For a 15 year period i was an exhibitor as part of quad electroacoustic at the CES show. I know more about the politics of that kind of thing than you will ever know.
