If jude is going to go that far back, he might as well start fresh. In addition that database was a few versions old for the current vbulletin software, so it could be upgrade city, and lots and lots of additional bugs all over the place. Plus all the features and changes since then. No matter what jude does, unless he can get the database fixed, there are going to be lots of unhappy people. Then that effects all his user counts, his page rankings, all sorts of stuff. Ugly, really Ugly. No backups in a year. What a maroon.

What's up with dynafet boards these days?
kevin gilmore replied to Icarium's topic in Do It Yourself
Yes it will, without any additional compensation, i have one running at a gain of 4 now. You can certainly build it with 2 devices per channel. But i like the sound of the renasys fets over the international rectifier versions, and they are not as strong, so you really should do 4 of them. There are 4 different versions of the boards, and when i'm sure of the pinout of the lsj109 there will be 4 new versions. Build what ever turns your crank. Then again compaired to the toy output transistors on the (well you know) you could probably just build it with one set of output transistors. But where is the fun in that. Need to be able to drive k1000's to painfully loud levels. -

Nope. If you want to do that, find a raptor with the original power supply. Cooks eggs just fine. -

I'm waiting for linear systems to get their butt in gear and actually deliver on lsk109's. Then the floodgates open. The lsk389 is so much better than either the 2sk389 or the individual versions used in the B52 that it is worth waiting to do it right. I have a dynafet prototype with 2sk389/2sj109 and it is kickass. No matching of parts will be necessary, just stuff the board and it works. -
Lets be fair, the parts cost may be as high as $500 which makes it only 6 times the cost of parts. There are 2 chassis afterall Very interesting on ray's website, all internal pictures of the apache have been removed. And no internal pictures of the power supply have ever surfaced yet. Double the output impedance of a hr-2. Very sloppy bass with lower impedance headphones. The M^3 is a far better circuit with way more output power than the apache.

woot has power conditioner! (11/14 only)

I bought a dirt-dog because i could not handle the mess in my garage anymore. It does a great job. So i bought a roomba and a scooba to clean up after the dogs. (and drive them nuts) They should be here tomorrow. -
Can you just imagine what jude looks like, and smells like after 4 days in that datacenter... Euwwwwwwwww... At least he does not have to shave
-
I have not published the KGST yet. I think there are 3 versions. Have not even done a board layout yet either. When the lsj109 finally appears, there will be many new designs, published. The KGST does not use a lsj109 anyway. Lots of new designs on the drawing board and prototypes built in fiberglass lunch trays... For years and years even
-
The KGBHSE and the KGST are two different things entirely. Over at that other site that is still down i posted pictures of my KGBHSE. I'm pretty sure that all that is left is for the real chassis parts to show up. And they are probably roughly on schedule. But you know justin, they will have to be absolutely mirror finish perfect. Pretty sure the whole first batch is sold out, but contact justin to see if any are left. here is a few of the pictures. http://gilmore.chem.northwestern.edu/g9f22761.jpg http://gilmore.chem.northwestern.edu/g9f22763.jpg http://gilmore.chem.northwestern.edu/g9f22764.jpg

Not a single moderator over there that has ever owned an electrostatic product. Ray can't steal any useful designs without untold amount of grief, and is completely incapable of coming up with anything on his own. Therefore the mods ignore the stax threads.
-
Great stuff. Absolutely true.
-
Filburt and everyone else is absolutely correct. The only reason that the gain of 11 option is available is that it is a copyover from the hornet design. That high gain is designed for sources that have an output voltage of only 100mv or so. This is clearly stupid as the internal dac has an output of way more than that. Given the 4.0 volts (absolutely fully charged and even overcharged a bit) and a rail to rail opamp that looses .4 volts, the absolute maximum output voltage is going to be 3.6 VAC Peak to Peak.

I think the record is that one guy in iowa with 500,000 watts (gets bigger each year) At the chicago pricing of .11 per killowatt hour, that is about $55 per hour, 4 or so hours a night for about 45 days is about $10k.

No Bugs Bunny?

Billy get those things outside where they belong. Get a couple hundred more to go with them. THINK CHRISTMAS DISPLAY!!!!! You know you want to... Got to compete with all those whack jobs that end up on tv showing off hundreds of thousands of watts... Shape of a giant headphone.... You will get on tv for sure.

Billy has on a number of ocassions proven to me that he is in fact mature in some situations. Especially when it comes to running his two businesses. Usually when I have met someone that is immature, they are so in every facet of their life. So there still has to be some other explanation. Anyone want to speculate??

It was a joke OK. In another thread tyrion says there is always some truth in every joke. If i've offended anyone that is actually bipolar, it was completely accidental. My sisters ex was diagnosed with a very severe case of tourettes. So i know what that is really like, and looking back on it, it completely makes sense. A former friend of mine i now think has the same thing, plus being a manic depressive. Seriously though, it might actually explain some of billy's actions. If you have seen billy in action you know what i'm talking about. There has to be a rational explanation... There are a number of people I work with that are definitely bipolar, and admit to such. No billy, I'm not picking on you. I just want you to get the help you need
-
Actually I think he is. That or tourette's syndrome. Or both. Certainly would explain a lot of billy's behaviour.... Being bipolar isn't really a bad thing. Except when as a tenured professor in colorado, you give away hand made explosives in class for halloween... (and get arrested in the process)
-
Leave my good friend billy alone He's bipolar don't you know Similar to "Mas e Minos" (ok, lets see if anyone knows that cartoon reference)

Enough coffee now Meta42 for $875... NOPE. Worse than that, much worse than that http://headwize.com/projects/showfile.php?file=opamp_prj.htm figure 11c. with much smaller transistors, otherwise identical. (+/-15 volt power supplies) CMOY FOR $375 NOPE. That is the meta42 except with buf634's instead of the el2001...(SR71 with +/- 9 volt supplies) or just an opamp (hornet) with a rail splitter (single 9 volt supply) or just an opamp (tomahawk) with +/-1.5 volt power supplies or just an opamp (predator) with a rail splitter (single 4 volt supply)

That is just the tapedeck and robot. Lot more to it than just that piece.

And eat up 1000 sq feet, and consume HOW MUCH POWER. OK, that is not quite fair, an EMC box will do it in 4 rack panels. One on line raid'd and mirrored set, One off line set that runs the backup on 5 or more 600gb dlt drive in parallel. Then it would only take about 6 hours. Plus robots and stacks of tapes. Price is still nasty. Want something that sits on a desk, makes no noise, and can do at least 200 GB /hour. Without changing tapes!

I'm feeling fine billy. Still happy from massive hunk of moo from mortons on saturday. Combined with huge shrimp alexander. Been working on a failed drive in a 3T raid set since friday. Started friday morning and just finished about 15 minutes ago. Sure would like to find a way to back that thing up in less than 1 week. (removable media) At least the hr-2 is built well with none of rays famous major errors. 1) It can't cook eggs on the top panel. 2) No noise from the switchers because there aren't any. 3) No mother fucking huge caps that do absolutely nothing. On the other hand 1) not only is is not pure class A, it can dip into real class B due to layout error with temperature compensation diodes. (fixed in apache) Ok, go and look the rest up. I need coffee! There billy, you happy now...
