Looks like another case where clean AC wall power is demanded and supposed.  Since they use triode output, I wonder if the "gain path" of the pentode is "wired triode", as well, or if they just want the extra gain to scrub in the upcoming RIAA; or maybe they are just "getting a jump" on the RIAA with the pentode feedback?  7788 is optional for the pentode.  I think they said RIAA is LCR shunt, off the output stage.  Seems like most current correctors use a "second stage" of 3 stages for this.  RIAA correction choice must factor in to the (high...) 2k Ohm output.  Nice, low values for the caps, although still not in air cap territory...
