It seems rather a waste to use these tubes as simple common cathode voltage amplifiers. Their low Rp and relatively high filament power provide more advantage in other topologies. They also exhibit a much greater heater-cathode breakdown than is commonly known. This can have distinct benefits in high-level SRPP, where the upper half of the stage can utilize anode voltages of 450V or more without difficulty. However, for simpler tasks, other tubes are less demanding and more routine to utilize and tweak.
