Cathodyne PI

Cathodyne PI
Can you direct couple the grid of a triode used as a cathodyne PI to the plate of the preceding stage? Is there some advantage to AC coupling in this configuration ala the Fender Tweed Deluxe. Might it work better to use a 12ax7 with the first triode as a standard gain stage direct coupled to the second triode with matching plate and cathode resistors? All input is appreciated.
