That's correct ... AC goes into the tripler. As another person mentioned, potted
triplers for horizontal frequency will not work. You need film caps and 2 kV or more diodes.

Oh yes! IF you look hard you can find used HEathkit scopes and modulation monitors that will
have the necessary stuff in them. These may or may not be cheap.
