I have everything to build a pimeta except C6, I'd like to try to get it going without C6 before ordering C6 since I want to get it done and tested. If not populating C6, should I simply short it out? It looks like this is necessary to complete the feedback loop.

I think you would need C6 and no, you cannot short it. It is there to stabilize the ground channel.

What op-amp are you using?


Quote:

If the unity gain crossing of the op amp is near the gain-bandwidth of the buffer the over-all phase lag of the circuit will consume most, if not all of the available phase margin, and oscillation will occur. For this reason it is important that the buffer has a GBW significantly larger than that of the op amp, so that loop performance will be determined solely by the op amp.
