May 27, 201511 yr That psu is just one of many BH variants that I've drawn up over the years. 500V input caps and 450V output caps. You can get it through with some care (that's what she said.... ) but a drill does help. Just make sure to deburr... even the 1486?
May 27, 201511 yr What kind of press, Joachim? Avoiding the expense of PEEKs seems worthwhile (apart from the torque discussion). Edited May 28, 201511 yr by GeorgeP
May 28, 201511 yr I use a very small machinists vice like this https://www.southern-tool.com/store/wilton-super-precision-tool-makers-steel.php mine is about 40 years old, and even better built, no idea where I got it Edited May 28, 201511 yr by kevin gilmore
May 28, 201511 yr This one looked really good... until I saw the price. Will try to find something similar under $100.
May 28, 201511 yr Lots of stuff here http://www.shars.com/products/toolholding-workholding/vise?limit=30&p=2&price=-100
May 28, 201511 yr even the 1486? The 1486 is partially insulated so you just need the ceramic insulator for them. Better yet, use the KSA1156 where you can.
May 30, 201511 yr So, it appears Justin Wilson knows about his stuff, a little bit... http://www.head-fi.org/t/439657/headamp-blue-hawaii-special-edition/7200#post_11647599 arnaud
May 30, 201511 yr Now you know why we keep increasing the clearance of the ground plane around the traces. The KGSSHV power supply was he biggest headache as there we have roughly 700V of raw DC floating around. My longest bit of troubleshooting was last summer, two months to find a phantom noise in one of my BHSE's. Came and went but was finally tracked down to the TV antenna causing a ground loop.
May 30, 201511 yr i thought it was an arc in the pic, but it was a whisker that i missed. had that whisker not been current limited by a 1M resistor, it would have most likely blown apart
May 30, 201511 yr that's what Justin gets for using quality made in usa circuit boards. time to use the Chinese crap.
May 30, 201511 yr The inside of that blue Hawaii looks amazing,never seen the lid off the Psu though,be interesting to look at that too,Think I would leave the covers off,make it more exciting tip toeing around it plugging the headphones in and out,joke
May 30, 201511 yr i thought it was an arc in the pic, but it was a whisker that i missed. had that whisker not been current limited by a 1M resistor, it would have most likely blown apart Are cats doing your soldering now Justin? Good, and apparently lucky, find!
May 30, 201511 yr that's what Justin gets for using quality made in usa circuit boards. time to use the Chinese crap. You wouldn't say that if you just had the day I had trying to track down the short(s) in a board.
May 30, 201511 yr i thought it was an arc in the pic, but it was a whisker that i missed. had that whisker not been current limited by a 1M resistor, it would have most likely blown apart I feel even luckier
May 31, 201511 yr You wouldn't say that if you just had the day I had trying to track down the short(s) in a board. i've had one that i could never find even after knowing exactly which trace was shorted, and looking at it under a microscope. it had to be internal. kevin's idea of blasting it with high current did the trick i also had a board where I had paid for the flying probe testing, and a short was found - i could see where they used a blade to remove the short. However what they didn't do is test it a 2nd time, because there was actually a 2nd short on the same trace. I didn't consider that possibility so that one took me a while to figure out Edited May 31, 201511 yr by justin

March 8, 201610 yr I was moving my setup around and unplugged all the cables without paying attention to how they were plugged in. Is there a certain direction that the umbilical cord needs to be plugged in? or can someone send me a copy of the instruction manual? Don't know where my manual is right now.
March 8, 201610 yr On the Nate bhse, it only works one way. There is a male and female end. If it is the same on both ends I'm not sure how it could be directional.
March 8, 201610 yr On the Justin BHSE, there is also a male and female end. I am concerned about different rotation of the cord when you plug it in (it plugs in with a 3 by 3 grid). Perhaps I should look closer, maybe there are some grooves so that it can only plug in one way.
March 8, 201610 yr ^^ What he said, there's only one way to plug the cords in on the BHSE, Shelly. There is also a key (and matching slot) on each connector receptacle pair so you can't get it wrong unless you apply serious anger and break something.
