Correction... the screws that hold the heatsink brackets to the heatsinks are 3/8 long, not .5 long

So here is the current plan. I should have 8 sets of tops and bottoms done by next tuesday (then i'm out of material till i get some more) and the knobs by wednesday, then 8 sets will head off for polishing. When i get them back (3 to 4 weeks) i'll send half for anodizing because that is the batch size the guy wants, (another 10 days) and then 4 will be available. When he drops off the 4, i'll give him the next batch. After that there will be only one batch of 4 left. So who wants one of the next 4 chassis. And include which kind of stax jacks you want. PM's ok too.

From the man with 4 billet machined aluminum krell remotes. DEFINITELY... Now the at material cost is ok, but i still have to pay for machine time at $72 an hour starting sept 1. (up from $68 ..) Takes a while to machine titanium.

http://gilmore.chem.northwestern.edu/kgsshvbomas.xlsx will get to the rest of it today. My server will go up and down a couple times today for updates...

actually i have changed to a diferent current source, but its an easy fix. I actually have 3 versions, not really sure which of the 3 will end up in production. I just got the fixed bom in an email, will post soon. Cleaning the saeco automatic expresso machine, and that is obviously more important... Since i'm addicted to coffee...

OTL fully direct coupled DHT. This is the way Lots and lots of power supplies.

I'm pretty sure its a 1.5 amp slow blow. (for 110 vac) But it might be a 2 amp. Too lazy to go and look. Definitely not more than 2 amps. updated schematics with a couple of resistors labeled as to power, and default of .5 watt added. I will have to look tomorrow on the fuse... Its never blown the fuse yet. Not even with 24 hours of CJ.

Another year older, and probably not any wiser.

A german company Lambda Physik (now owned by coherent) still builds lasers that way. With hydrogen thryatrons as the triggers. I don't like messing with those things they scare me. And i don't get scared very easily.

One major other thing i forgot is that a lot of gaot attacks are due to STRESS. So you need to reduce your STRESS level. Drinking booze definitely will make it worse. Lots and lots of water makes it better.

But then you have to go to stacked current sources.

pure water is 10**18 ohms per square. So a 6 foot long piece of tygon tubing (.5 od) filled with pure water ends up about 500 megohms. obviously tap water may be hundreds of times worse, so probably 10 megohms. Which is about 5ma at 50kv. So a grounding block at the end of the tubing makes the water safe. Still, you gotta pay attention when you are doing potentially stupid shit. 5ma can definitely kill.

You would need DI water or similar. NO calcium or magnesium... Its only 500 volts. Or just buy a bunch of heater resistors, make a string out of them and hang them someplace safe. I run my Xray's on DI water, and the anode is at 50kv. The sector mass spec i just dumped in the garbage can ran 30kv on the FAB tip on a garden hose (the chiller toasted itself) Please be careful.

well if you don't have gallons of fluorinert laying around. Obviously be REALLY careful doing this. alternatively some really good and pure low parifin oil like they put in the old xray tanks. The 60 volt supply is 80 ma total referenced to the -500 rail. The 12 volt supplies i doubt are more than 20ma each. The relay probably pulls more than that.

Not really true, lots of successful audio couples in the business. Krell (well until they had the company taken away) Wilson (the other wilson) Klipsch (until death do us part) Pass (still plugging and chugging) Manley (well that one did not end well) Borbeley (very successful for 26 years, just retired, shutting down the business at the end of this year) i'm sure there are others

NO knobs on the blowtorch. Just a touch panel and a remote.

NICE NICE NICE... The testpoint things are a GREAT idea. Whats the part number. People should do this, a better way not to get knocked across the room. Also fully plastic adjustment tool an absolute must.

well justin could ship them to me first. Might be kind of silly, but 4 oz of feet added to 39 lbs of chassis is probably cheaper than 2 packages. justin is less than half my age. And still in shape. And still single. Hey ladies... good catch here... solid future... (runs and hides )

No deadline on items like that. I would order material as necessary. And i was not paying attention on R50... Thought you were talking about the 500 volt supply. which is 490k.

this pic should do everything for you http://gilmore.chem.northwestern.edu/t2power3.jpg R50 sets the output voltage. so you probably want to go to the standard value of 287k which should be a tad under 500 volts, but 300k would certainly work. All of the .6 inch resistors are supposed to be .5 watt. will update the schematic when i get home if i remember. pick load resistors out of your junk bin, and test at say 60% of max power. make sure they can handle the power, or dump in a plastic pail filled with water and stay away.... The 47 ohm resistors are just to ground the input filament. Would be the same as having a center tap on the transformer... In the middle you can see the bare wire connecting circuit board ground to the chassis nut close to it. Don't forget this.

no spare heatsinks. But high probability of a complete extra chassis set without a matching circuit board. Don't want to sell the heatsinks without the fronts/backs as i only have complete matched sets.

allopurinol is cheap and very effective for most people. uloric is better, but is currently very expensive even with good insurance. There are many ways to get the protein you need without eating red meat. i've cut my uric acid levels by 75% over the past 5 years. Not fun. Try to stay away from the steroids. The more you take them, the more you need them. And they cause eyesight and liver problems.

The problem with this is that these scales are designed for 75 lbs or more. So my 200 gram calibration weights are kind of useless. Besides which, if its under i'm happy, and if its over, they would not give a crap about it. But it might be interesting if i can find a calibration weight in the 10 pound range. Actually i have a 100 oz silver bar that would be perfect, just need a few more.

fedex standard, wheeling il to sydney for 40 lbs $459 (7 days) $506 for 3 days. Overnight, it costs more than what is inside. By the way the correct tracking numbers begin with EG the CP numbers are the customs numbers

The problem with internet postage (i have a suitable printer) especially with stuff going outside the country which all 4 of these did, is all the customs forms, and the weight. I know my scale is accurate, as it matches the one at work, and the package really is 39.5 lbs. But i got lucky and got the really messed up scale at usps which weighed the packages at 33 and 35 lbs (they are absolutely identical in contents) and therefore saved a few bucks. So now in total (not counting gas) but counting everything else including bubbles and the packaging for the boards, i'm down to a loss of a little less than $8. Fedex seems to be in the other direction. Their scale always weighs over the real weight. I wonder if that is deliberate. At least fedex inside the usa is going to be only about $40 instead of the package to Australia which was $235. And fedex international is way out of line price wise. Birgirs package was even higher priced.
