Introducing THE PHONO STAGE by Progressive
Engineering. Mike Paschetto has come up with a Statement tube phono
preamp that takes it "to another level."
The preamp uses a split passive RIAA circuit as the base for the design, designed
by none other than Sir Paul Joppa. The gain triodes are Russian 6N1Ps with
C4S (Camille Constant Current Source) loads.
The output is fed into a C4S'd 12BH7 running as a cathode follower, and the
whole thing is shunt reg'd by a hybrid 5687/7119 regulator, which is in turn
loaded with C4Ss. The DC heater supply is heavily filtered, including dual
chokes.
According to Doc B himself, "this preamp is nice and quiet, with plenty
of speed and extension." If you want a no-holds-barred phono preamp,
look no further. Limited first production run - Please Inquire
