The diode improves the sound by some unknown (to me) means. It is an idea that I first saw on a webpage authored by an Australian guy named Dennis Grimwood. Using the diode in that location makes for more sonic clarity with a tetrode/pentode that is connected for triode operation. The usual connection fo the suppressor grid is to the cathode, although others connect it to the plate.
