Whats funny is that 2 of those vcaps are in series which is a really bad thing. Especially when the caps are already rated for the required 600 volts.

tomorrow came quick http://gilmore.chem.northwestern.edu/sdsgasps.jpg 2 of these in the box. Has to be. Or something extremely close probably with more capacitors in a RCRCRC type thing....

From information just supplied from voltron, (no pictures yet) A knob on front selects 1,2 or 3 gas tubes per channel. But the gas tubes can only run at about 10ma. So there has to be some kind of pass element. And knowing mikhail its a big FET. What has happened is that the FET is shorted putting full supply current into the gas tubes thus making them go pop. Inside pictures will definitely confirm. Partial likely schematic tomorrow.

ES1, ES2, ES3 .... all the same stuff. Exactly the same stuff. At least from the pictures i have seen. Now the voltmeter option, the fancy front panel option, the digital attenuator option...are all additions to the same exact schematic. Optional wallwarts both internal or external to the power supply not shown. Don't have internal pictures yet of the Tube regulated neon glow power supply.

I did the schematics in an attempt to help all the people out there trying to get their shit fixed. So yes they are public. Someone needs to help these people, i'm doing the best i can short of actually fixing the stuff myself which i just don't want to do. The schematics were generated in part from the pictures above, and a bunch of other pictures that are not public. There is just so much fail all over the place...

this is the right way to do this Wilson Audio: Audio Excellence, High-quality Audio Components, Luxury Speakers 30 watts will blow the windows out... Or build one yourself.

chip amp for sure. Notice that the power input is AC. Therefore the things on the heatsinks have to be regulator chips, 2 for each channel. 5th one is likely a 5 volt regulator to control the switching.

Yep hdmi seriously sucks. I've built small metal brackets, custom for each device. Attaches to a nearby screw, and holds the cable perfectly level about 3 inches away from the connector. No problem so far. For the long runs of which i have 2, i'm using hdmi to dual 100T ethernet converters. Works great with cat6 cable even at 1080p.

I have every one of the sacd's on that list, plus the concord jazz stuff most of which is not listed. Great music.

nope, not really. But in larger sizes both the lcd and plasma's end up pretty close in weight, and pretty close in power too. 65 inch displays average about 600 watts. All of a sudden one of those 1kw xenon bulb projectors does not sound unreasonable

Well i can't say i actually paid for this, but its mine, all mine. 125 watts CW at 2450 mhz http://gilmore.chem.northwestern.edu/microtherm.jpg UL approved in 1957. And therefore medically safe Works great. Only 300 hours on the magnetron.

So i contacted my friend at sony about this... His answer was completely not what i was expecting. The dsd1796 and the "cheap" opamps are used for one thing and one thing only. wait for it... wait for it... this is a headphone forum afterall yepper, the built in headphone jack. What a waste of extra parts... I've ordered the schematics to verify this. Sony is coming out with a new $3k beast the very beginning of next year. Also a hats balanced digital preamp, also about $3k.

There really are only 2 good analog pots in the entire world. RK50 and P&G. Both seem way to big for a portable. Digital attenuators are going to be the only way to assure accurate volume tracking over a wide range. Justin has decided to use a mono analog pot and a microcontroller to digitally emulate a stereo pot. With perfect tracking and very wide range. Should he want to, it would be easy to replace the knob with an apple style touch slider. Ray has decided to use the 3 position alps switch and no micro to do the same thing. Some people are not going to like the up/down button version. Ray blew it, because for a few cents more he could have integrated balance into that switch. But i really don't need to give ray ideas.

Its a 4mv with 64 meg of ram and internal 20 meg hard drive for fonts. As such it is way fast. I got it cheap directly from the HP salesman 13 years ago. I would actually like something smaller and get back some of the desk.

Not mean at all. As long as ray continues to paint his chips and lie to people about what is inside, i'm going to do my best to spread the truth. Ray is using a 7 year old chip. Why? because the word firmware does not seem to have entered his vocabulary yet. How about the fact that ray still does not understand how to safely charge lithium-ion batteries. And yes, many of ray's fanboys are fools.

Bingo x 5.. Many thanks... As usual its the keywords that are all important in the search. My master machinist knows where to get the spring loaded handles...

You have no idea what qualifies as a TA these days. I'm not looking for cheap. I'm looking for something pretty.

I know they are a standard issue thing, but hours of searching have found nothing. If you have a catalog name/part number that would be great. 1.5 inch ID. I did find the drumset clamps. If i can't find what i want, those are definitely the next in line.

For what is to become the ultimate headphone stand... http://gilmore.chem.northwestern.edu/headstand1.jpg http://gilmore.chem.northwestern.edu/headstand2.jpg I'm looking for more of the 2 piece tube clamps pictured. 1.5 inch diameter. These have to be a stock item somewhere, i just can't find out where.

The superman glasses are at the beam line at argon national labs.(synchrotron) Which i have access too. But if i pulled a stunt like this on the beam line i surely would get my ass thrown in jail for a long time. This is the 2.5kw version Rigaku Americas -- Products -- Generators -- FR-E+ SuperBright The 50kw version is much more fun.

The volume knob on ray's new piece of crap is an alps SLLB5 http://www3.alps.com/WebObjects/catalog.woa/E/PDF/Switch/MultiControl/SLLB5/SLLB5.PDF I'm virtually 100% sure now that the digital potentiomenter chip is a dallas semiconductor (as in maxim) ds-1802 http://datasheets.maxim-ic.com/en/ds/DS1802.pdf One of the 8 pin chips is a rail splitter and the other is a 3 volt capable opamp. Which means once again.... flea power output. OR lots of clipping... No usb charging chip. Guaranteed ground loop when using the computer to simultaneously power the amp and the sound card as the source. Yep, typical ray... better than some of his stuff, but overall a D- Did not even need my new (and currently broken) 4k x 4k Xray machine... Getting a rotating anode machine in about 1 year (50Kv at 1 AMP!) Won't even have to take the circuit board out of the case...

It will work, but the regulators may be running at the very bottom of their regulation range. So noise and other problems might show up.

The things in the melos drifted more than 1db just by waving paper over them. The temp curves of the photodiode and led would have to match extremely well to make this work. Since the two are completely different semiconductor processes, this is almost impossible.

LDR's suck when it comes to stability WRT temperature. Anyone that has ever had to fix a marantz 10B would know this. Bad idea for portables.

The wolfson dac definitely is native dsd compatible, but if you read thru the marketing bullshit, the term DSD is never ever used. Just high resolution WAV files. This is a boat anchor from the start. Not going to be upgradeable to DSD without significant amounts of work, and licensing. No way un-encrypted i2s link is going to be allowed for DSD. Unlikely that PSaudio actually designed this, someone else did. Another antique right out of the box. You would be much better off buying the latest dCS stuff at 33% of retail and then bolting it to a late model sony for about the same price.
