The big heat-sinked paralleled transistors _are_ N-channel depletion-mode FET's. I used the Fluke to measure the channel resistance of the pair between source and drain, and got about 0.8 ohms. With a negative 1.25V applied to the gate using the Heathkit VTVM's ohmmeter function the channel resistance of the pair shot up to around 80 ohms.
