I just want to add that the MC1496 has most parts for the actual 4 quadrant
core in it. I'm tempted to put the diode-preshaper, that the 1496 compared
to circuit presented lacks, in front of it. That should make a cheap but
linear ringmod. No need to go fully discrete as you did. Ah, and it should
also be possible to add that to an OTA or discrete diffamp as well.

 René
