The McIntosh circuit topology was not Ultra-linear. They had a patent on so-called "unity coupled" amplifier circuitry, which was the basis for all their tube designs from the MC 30 on. They made use of a special transformer winding technique along with a cathode winding to provide large amounts of local feedback around the output stage.
