Hello Markus,

I am now using an MCP1404 so I can delete the 5V regulator

http://www.gatesgarth.com/MCP1404.pdf

So am I ok using another pair of 15K to pins 2 and 4 up to pins 6 (12V
DC  +)?  Thanks,  this  is  all  rather academic, given the latest U3S
firmware  allows  direct output of two signals from the Si synthesizer
180 degrees out of phase I just fancied seeing if I could reduce the
component   count of an amp.  (Just fancied fiddling....probably not a
good idea, but I need to learn ;))  Thanks Markus, happy
New Year to you!
