Not only that..The primary load is split between the cathode and plate and it's less than half of the typical primary impedance of most KT88 amps in the case of the Mc275.Also, no amp is going to flat into a reactive or capacitive load,tube or SS. In the case of a SS amp,when the impedance rises,the power drops and when the impedance drops,the power rises.With that,we will see peaks and dips in the response curve and this is why we always use a resistive load to measure impedance.
