PRR, I am sure that i am unable to use the back to back transformers to power the regulator circuit but my thinking was the REGULATOR part of the circuit could be floating but this does not seem to be the case.
I bypassed the regulator and clipped a 9v battery to the boost circuit and it worked well. So now my thinking is that like a normal FX pedal the ground of the FX and FX power supply use the amp ground as part of its circuit
So a separate small transformer used to power the regulator is required as you have said, the regulator and boost circuits should have the same ground.
The first schem is what i thought i could do by just tapping off the 15v and 0v tap to power the regulator.
The second schem is what i think i NEED to do.Thanks
