In Reply to: The gain stages in the Jolida are ICs posted by garymuffley on July 11, 2023 at 16:54:21:
Certainly all the gain surrounding the phone EQ is from ICs but the last stage of each channel is a so call Totem Pole (or SRPP) made from both halves of a 12ax7 and it does have gain. It is considered one stage but the first triode of the Totem Pole is the gain part and the second triode is a cathode follower output.
