To start, this will be a DIY system where I'm going to sell the PCBs I'm laying out and panels if people want them. assembled modules will come later if there is sufficient interest.<br /><br />Thanks for the comments.David Ingebretsenhttps://www.blogger.com/profile/13684454187281311588noreply@blogger.comtag:blogger.com,1999:blog-2183367221470973675.post-54795106005434187852010-08-09T15:11:55.298-07:002010-08-09T15:11:55.298-07:00You'll need a GND socket when you want this sy...You'll need a GND socket when you want this system to interface with another system which doesn't use grounding at its sockets, like Serge, Modcan A and Cynthia. <br />Simply connect both GND sockets (pref' w/a banana), resulting in both grounds being "equal", and thusly avoiding hum and other problems.<br /><br />Likewise, similar systems (say, different Serge panels powered by separate PSU's) are connected in the same way, so they can 'talk' to each other.<br /><br />I'm often surprised most Euro/Frac/etc manuf's don't implement this, because it's easy and doesn't cost more than 70 cents.<br /><br />IMHO, this would be a gentle & friendly nod & wink to all those banana-people out there. :-)<br /><br />Of course, if this is going to be a DIY system, then those particular folk can take care of themselves easily, and I didn't say anything.Guy D2https://www.blogger.com/profile/08419261626869296454noreply@blogger.comtag:blogger.com,1999:blog-2183367221470973675.post-82113835259906511012010-08-08T23:32:56.269-07:002010-08-08T23:32:56.269-07:00I agree. +/- 12 without having to trim a regulator...I agree. +/- 12 without having to trim a regulator would be ideal. It all came up when Nyle and I were discussing the V/Oct tuning and he said he had to re-tune the prototype I gave him because he was using a +/-12 volt supply. We talked about it and decided we should maybe just make sure they run on +/-12 volts. <br /><br />Nyle confirmed there is nothing special with the +12 -10 configuration.<br /><br />What or where would you want a GND banana socket? I'm not understanding.<br /><br />Thanks! I'm going as fast as time and money will let me :) <br /><br />I've got the Gerber files ready to go and as soon as I give them a final look, I'm ordering what I hope will be the production version of these first modules. There are a few comments, like yours, I want to clear up first, too.David Ingebretsenhttps://www.blogger.com/profile/13684454187281311588noreply@blogger.comtag:blogger.com,1999:blog-2183367221470973675.post-60113347581392001042010-08-06T10:07:25.206-07:002010-08-06T10:07:25.206-07:00+/-12V would be super.

Like STS does on their PSU blocks.<br /><br /><br />Keep going !Guy D2https://www.blogger.com/profile/08419261626869296454noreply@blogger.com
