To the extent that there can be anything "new" about patching together well-worn circuit elements in a different way, I believe this design is "new."   Like the cmoy, it uses a passive ground splitter. Like the 02, it uses opamps in parallel to double output power. And like nothing else...

I am building two CMOYs in the same box, and I had a +/-15v dual supply lying around so I tried hooking it up.  I ran the positive and negative wires to their respective places on the opamps and the output from the center terminal to ground.  If I have only one opamp insterted, it works great...

Not much of a "mod," really.   Since I could only find linear, dual-gang, 10k pots here in Korea, I am planning using the "better volume control" mod from ESP.  Basically, put a resistor going to ground after the pot to make the linear curve more logarithmic.  I am using a 1.5k resistor.  ...

Hi, I want to build a box with four headphone amps, each with their own independent inputs. The cmoy looks good, but I would rather have one main power supply than four 9v batteries. Any ideas on the best way to do this? Just to clarify, I do not want a distribution amp. Rather, I want basically...
