Re: KRAFTWERK Power Supply BUILD THREAD

Looks like the 2A slow Blow fuse did the trick. I was getting close to proper voltages on all the rails..... Then I blew C1. :shock: Getting 28V from the transformer, which should be fine,.. Will have to check to see if there's a short somewhere. Hope something didn't short out against the case........

Re: KRAFTWERK Power Supply BUILD THREAD

Awesome. Thank you. I figured that it was the transformer pulling current, I had no idea it would be that much though. Good to know! And I'll let the secondaries down if it's the end of me. Thanks for the help

Re: AC/DC & POWERSTATION KIT BUILD THREAD

Thanks joe,
But why aren't the trim pots changing the doc voltage at all? Or would I have to adjust them down quite a bit to see a change? Either way, I think I can use it as is, I'm just powering one API type pre and I think phantom should run off of 42v, yes? Thanks for your help!

Re: AC/DC & POWERSTATION KIT BUILD THREAD

Hi Joe, I've bought about 15 of these AC/DC boards from you, mostly the V3, and had good luck with them. This last one is giving me all sorts of troubles though, it's a V4 board as you can see in the pic. I'm using a Triad VPT18-1390 transformer http://www.mouser.com/ds/2/410/VPT18-1390-224254.pdf w...
