As I stated before, I'm familiar with these "rod" pentodes, and I doubt they'd work well in phantastron circuits. The electron is a sheet beam, and the rods act as a lense instead of a grid, leading to a very low G2 current. Since the phantastron circuit depends on varying the plate/G2 current split, I don't think they'd be suitable. They're a lovely piece of engineering, and are great for low-noise use (since they don't have grids per se, they have much lower "partition noise" than gridded pentodes). - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
