Unhappy ACA Version 1.1 - Need new feedback resistor value

At Burning Amp Nelson presented ACA version 1.1; R15 was incorporated in the PCB, and there was a change to the feedback resistor; did anyone catch what the value was?

By feedback resistor do you mean R12, formerly 68.1K? That would seem to violate Nelson's 10dB feedback rule which causes higher order distortion products to be produced.
