kevin gilmore Posted January 22, 2010 Report Share Posted January 22, 2010 The panel is .25 thick just like the real stuff. Some of the stax plugs are a bit larger than 18mm, so if i recess it then i have to machine a donut around it. Will try with the O2 plug later. The pins in the stax jack are already recessed about .05 Quote Link to comment Share on other sites More sharing options...

Will try with the O2 plug later. I asked this question in the Stax thread, trying to do my panel with Marc's jacks...... apparently, the biggest Stax plugs are 18.5mm in diameter.

kevin gilmore Posted January 22, 2010 Report Share Posted January 22, 2010 original omega connectors and the stax extension cable are both 19.25 mm my original O2's are 18.88 mm the sr-003's i have are 18.93 mm Quote Link to comment Share on other sites More sharing options...
Beefy Posted January 22, 2010 Report Share Posted January 22, 2010 Well somebody's calipers are out...... I'll increase the size of my cutout a bit regardless, just to be safe. Quote Link to comment Share on other sites More sharing options...
spritzer Posted January 22, 2010 Author Report Share Posted January 22, 2010 I just measured my O2 (replaced the cable last year) and it is 18.53mm Quote Link to comment Share on other sites More sharing options...
Beefy Posted January 22, 2010 Report Share Posted January 22, 2010 Maybe Kevin is including the bulge of the keyway? Quote Link to comment Share on other sites More sharing options...
spritzer Posted January 22, 2010 Author Report Share Posted January 22, 2010 Probably Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted January 22, 2010 Report Share Posted January 22, 2010 Maybe Kevin is including the bulge of the keyway? Nope. Although that measures about .5mm Isn't a 5 digit digital mitutoyo digimatic a standard part of everyone's computer desk?? I have 3 on mine (different sizes) Plus a digital micrometer...

Beefy Posted January 22, 2010 Report Share Posted January 22, 2010 Gah! Lack of consensus is bad for Stax noobs like me...... Quote Link to comment Share on other sites More sharing options...
spritzer Posted January 22, 2010 Author Report Share Posted January 22, 2010 The Stax connectors are molded so there will always be some margin of error. Quote Link to comment Share on other sites More sharing options...
cetoole Posted January 22, 2010 Report Share Posted January 22, 2010 My o2mk1, sre-725, and sr-404 all measure about 18.54mm. Quote Link to comment Share on other sites More sharing options...
Les_Garten Posted January 22, 2010 Report Share Posted January 22, 2010 Nope.

I'm using the same caliper on my SR-003s and get the same number. FWIW. Quote Link to comment Share on other sites More sharing options...

spritzer Posted February 1, 2010 Author Report Share Posted February 1, 2010 Glad that's over... There are some errors in the BOM though, at least version 4 which I have. Quote Link to comment Share on other sites More sharing options...

Kerry Posted February 2, 2010 Report Share Posted February 2, 2010 Nice job Birgir! I'm in awe. Red is cool Anybody close to firing this up yet? Quote Link to comment Share on other sites More sharing options...
spritzer Posted February 2, 2010 Author Report Share Posted February 2, 2010 Red is indeed very cool. Kevin should be the first to fire it up and I probably won't be far behind. As for the BOM errors, there are no 6K8 resistors, instead there should be four 6k2's. The BOM listed 8*390K but you really need 12. You also require at least four more 10K units, probably more. Since it is such a common value it's a good idea to have some extra. I also matched the 22K resistors and interestingly none of them were over 22K. You need four matched as close as possible to 22K for the "zener" section. Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted February 2, 2010 Report Share Posted February 2, 2010 Hopefully the parts i'm receiving this week will complete the amplifier chassis. Still missing a number of parts on backorder for the power supply. Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted February 2, 2010 Report Share Posted February 2, 2010 More parts came in today. But still not all of them... Frustrating... anyway http://gilmore.chem.northwestern.edu/t2chassis26.jpg http://gilmore.chem.northwestern.edu/t2chassis27.jpg Quote Link to comment Share on other sites More sharing options...
spritzer Posted February 2, 2010 Author Report Share Posted February 2, 2010 I got an email today from Mouser and the last of the parts should be in stock in April. A long time but better then the late July date in the last estimation... Quote Link to comment Share on other sites More sharing options...
