Peltier effects are reversible with current direction

which suggests that the net effect should be zero for AC current. The junction is heated on one half-cycle, and cooled on the other.

However, you're saying that the transfer function is changed during each half cycle, which is a cause of non-linear behavior.

In that case, shouldn't the non-linear component increase with increasing signal amplitude? As the current increases, the total heat increases before reversing (the difference in the Peltier coefficients times the current integrated over the half cycle)

According to John, the effects he's seeing disappear at higher amplitudes, more akin to a crossover distortion effect.
