Attachment 1545 The above A47 diag shows a chip per channel design. Would changing the IC1b to IC2a change it to a chip per stage amp ? Also, notwithstanding the `cranckier` aspects of BJT opamps, will they suffice as buffers. I mean, if they were to be used as a buffer, they won`t need the...

Hi, First post and what a great site ! On to my question. Would it be possible to build the basic Cmoy with, say an OPA4132 and use 2 of the channels for the buffer, the other two for the stereo amp ? Does a schematic exists ? Many thanks, Andrew.
