Different cap values, different resistors value... What am I missing ? Is the ORS87 based on the U87i ?
And just how much difference (and in what direction) would you imagine the alternate values make?
While the idea is indeed based on the original U87 circuit, at least my version has a more... dare i call it, "sane" BOM (bill-of-materials). No point in needing 10-15 different component values, when five will do just as well (if not better).
