Earspeakers Posted February 24, 2015 Report Share Posted February 24, 2015 Because the saw costs $10, doesn't require software to use among other things? Yeah setting up and programming CNC isn't easy. It's a skill that takes practice and time like everything else. I have access to a full manual machine shop at work (Bridgeport, etc) and I prefer outsourcing to a professional when possible. Quote Link to comment Share on other sites More sharing options...
n_maher Posted February 24, 2015 Author Report Share Posted February 24, 2015 Ken, It's not uncommon for the shorts light to flash during testing. If you get a consistent short that's when there's a problem. The arcing that you witnesses might have something to do with putting a somewhat hot tube back into a live socket, but I'm not an expert about that. I'd try retesting that tube when it's stone cold and see what happens. Quote Link to comment Share on other sites More sharing options...
Torpedo Posted February 24, 2015 Report Share Posted February 24, 2015 Sorry for your bad luck, Ken. JJ had quality problems for some time by the late 2000's, but now they're doing very good and reliable tubes afaik. Better than most Russian and Chinese.

Laowei Posted February 24, 2015 Report Share Posted February 24, 2015 Are the JJ octals reliable now? Those were the ones with the problems. Quote Link to comment Share on other sites More sharing options...
Torpedo Posted February 24, 2015 Report Share Posted February 24, 2015 If they were made in the last 2-3 years, they should, but I'm just repeating what a manufacturer told me. Quote Link to comment Share on other sites More sharing options...
Pars Posted February 25, 2015 Report Share Posted February 25, 2015 (edited) Chinese trimpots? Has anyone tried these Bourns "clones" on ebay, such as this one? Funny, they use "Burans" but same font more or less as Bourns uses. I have a few of these and haven't noticed anything peculiar about them as compared to an actual Bourns, but wondered if there are any hidden gotchas, such as abnormal drift, etc.? EDIT: I see some posts on diyaudio about these, one in particular stating that the fakes are carbon vs. the cermet of the actual bourns. I'll buy the bourns...

spritzer Posted February 25, 2015 Report Share Posted February 25, 2015 I used some clones back in the day and they worked well enough even in a KGSS. I'm not going risk using them in my builds though. Quote Link to comment Share on other sites More sharing options...

I'd try retesting that tube when it's stone cold and see what happens. Thanks for the advice, Nate. I retested this morning and all 8 tubes passed with no bright, white flashing. Two of them still blinked during the K shorts test, but I won't worry about that now. I told the seller about this and that the tubes were all acceptable. I also was able to solve another problem today. The fuse blew, probably due to contact cleaner in the volume pot. That was a couple of weeks ago. I removed the fuse and put the holder back into the upright tube that holds the fuse. Without a fuse, I managed to jam holder in the tube. I was finally able to remove it today with the help of WD40 and a paper clip, that I straightened and put a small hook on the bottom. A new fuse is now installed. I'll install the tubes tomorrow and see how everything works. Edit: Installed the JJ's and gave it a try. My systems is now playing the beautiful, beautiful music again.

Laowei Posted March 6, 2015 Report Share Posted March 6, 2015 Looking for matched pairs or ideally a matched quad of C2M1000170D SiC FETs for an upcoming KGSiC Cabon build. Anyone know if these available anyplace to purchase? Quote Link to comment Share on other sites More sharing options...
s_r Posted March 6, 2015 Report Share Posted March 6, 2015 They're available on mouser last I checked. Quote Link to comment Share on other sites More sharing options...
Laowei Posted March 6, 2015 Report Share Posted March 6, 2015 Thanks. I saw singles at Mouser, but lack the equipment to do a proper matching. Quote Link to comment Share on other sites More sharing options...
spritzer Posted March 6, 2015 Report Share Posted March 6, 2015 I don't think there is anybody who will match these for you. The amp will work just fine with unmatched ones though Quote Link to comment Share on other sites More sharing options...
Laowei Posted March 6, 2015 Report Share Posted March 6, 2015 (edited) Thanks Birgir. Will give unmatched ones a try for a first build. Can always replace later if I like the amp with my SR-009. Edited March 6, 2015 by Laowei Quote Link to comment Share on other sites More sharing options...

spritzer Posted March 7, 2015 Report Share Posted March 7, 2015 They don't ship internationally... at least they didn't. Ebay might have something like that. Quote Link to comment Share on other sites More sharing options...
DefQon Posted March 7, 2015 Report Share Posted March 7, 2015 (edited) Thanks for that. Not sure they are willing to ship down under Aussie or a minimum order. I'm using the cable as single ended entry on the one opening side of my Sony ECR 400 which has been converted to a full blown e-stat. I'm a broke bastard and don't want to spend over $100 on a new pro-bias Stax cable from my distributor that I'm going to chop up so I've got a hand full of low HV rated male and female 6 pin DIN connectors and just need some wires now. I do have one old Stax 5 pin connector that I'll use to make an adaptor for. So far my ECR-400 is converted. Next up is my ECR-500, then a electret SR-60 which I've disassembled the driver to the bone and re-mylar'd but not sure how I'm going to connect the bias hookup wire to it. :/ No luck so far on ebay besides really thick lighting hookup wire electricians use, again not really applicable for the task I need it for. Something like an HV rated ribbon cable will do as well, again no luck on ebay unless I'm not using the right keywords for the right results.

spritzer Posted March 7, 2015 Report Share Posted March 7, 2015 Koss ESP950 extension cable works just fine. Ask somebody in the US to order a few for you and drop in an envelope. 1 Quote Link to comment Share on other sites More sharing options...
DefQon Posted March 7, 2015 Report Share Posted March 7, 2015 (edited) I hadn't thought of the ESP950 cable. How much are they and is anyone willing to ship one my way? Edited March 7, 2015 by DefQon Quote Link to comment Share on other sites More sharing options...

guzziguy Posted March 10, 2015 Report Share Posted March 10, 2015 I'm a taking woodworking class and my project is to build a turntable stand. Would anyone have recommendations for furniture spikes? They need to be adjustable (leveling) and be able to support at least 150 lbs. I'm building it out of white oak and the legs and shelves weigh about 80 lbs. I'm thinking of something like this from Dayton, but am open to other suggestions. Quote Link to comment Share on other sites More sharing options...
