Re: Too low (and decreasing) voltage when testing U24

Sorry didn't see this before now.. I simply didn't get the ground from the correct reference... Very silly. Did you fix your problem? Vincent also suggested to check if I had soldered R237 and R236, which I had. And if C79 and C80 was the right way. Don't know if that helps.. Good luck! Hi, thanks ...

Re: Too low (and decreasing) voltage when testing U24

For TM4 I could not find the 22K Ohm B type trimpot in the mouser BOM which I bought, but found a 25K Ohm (lin/log not specified) which fits with the Yocto1 build (http://www.e-licktronic.com/en/content/36-noise), so I used that. I see you solved this, but I checked this against the table I made an...

Too low (and decreasing) voltage when testing U24

Hello, Sorry for any noob-ness that might follow, but I really hope you guys can help me… I’m currently testing U24 before soldering in the IC, inspired from the Yocto1 build manual: http://www.e-licktronic.com/en/content/36-noise). I’m getting -15 V over green dot to TP4 at U24 in the noise section...
