Another sweeping generalisation!
Because a tube with the plate parasitic resonance BELOW the grid parasitic
resonance doesn't oscillate, a plain inductor can clear it up. If I remember
correctly, wasn't that what Jon Ogden found with his 4-1000A?
Of course, that's also 1930's technology - it's described in Terman's 'Radio
Engineering'.
But it isn't the universal panacea for all parasitic problems.
I suspect this thread will be pretty interesting over the weekend. Pity I don't
have e-mail at home, and I'm out Monday.
