The first is why do most wide band common cathode triode amplifiers use
plate neutralization and not grid? Usually they have a dual capacitor in
plate circuit and not
grid. It would be a lot easier to use a balanced grid circuit and a PI
plate circuit for
coupling.
The second is the best way to repair a B&W 850 whose ribs have
shriveled up and
disintegrated?
