This is the project page: http://www.akustische-kunst.org/audio/supergreen.html
The schematic: http://www.akustische-kunst.org/audio/supergreen/supergreen_schematic.pdf
and the instructions for the supply: http://www.akustische-kunst.org/audio/supergreen/supergreen_instructions.pdf
Well, for Ne5532 +/20 volt, 5 volt for relays, and 48volt for phatom.
So, the Ne5532 datascheme, tells a range from +-3 to +-20 volt. So, the opamps can be supplied for example with +-15 volt, but would be any problem in the circuit? I see one point that tells 17V on the schematic.
This doubt would be if for example I want to compare with other opamps, that need max +-15, instead the +-20 of the 5532.
Second question is about the 5v for relays, could avoid relays and use a current swith for phatom and hi/low Z? and forget the phase one, and so avoid the 5V?
