If you cannot get the simulation running in Tina try LTspice. It works there. Though instead of actual logic gates, I use two voltage sources with square wave outputs of opposite polarity. Maybe that will also fix your problem?

the more i get irritated by phantom power limitations
As I've mentioned before, I'm a great one for 'simple' inside the mic, and to move everything else (eq etc) further down the signal path.I've been tinkering with diverse variations of your OPIC circuits, and the more i play with them the more i get irritated by phantom power limitations. If all those tube mics have clunky PSUs that follow, why wouldn't we have dedicated PSUs for opamp based mics? This is definitely my next step. No more hustle with voltage multipliers, no limitation of how many opamps in a mic we get to use for various purposes, and the benefit of basically unlimited headroom is priceless.
I just want a mic where capsule's SPL limitation is the only limiting factor and i believe this is the way to go. Sorry for this rant, just had to share some frustration after several hours of LTspice desperation.
My post was certainly not a critique towards your original design which is marvelous. It led me to further experimentation for which i just need more juice.Of course if you want to include more op-amps internally, for other functions, then those figures would no longer compute.
No, I didn't read you post as being critical .... I was just intrigued to know why you needed more power.....My post was certainly not a critique towards your original design which is marvelous. It led me to further experimentation for which i just need more juice.
