I remember looking at a Princeton Applied Research Model 113 preamplifier in about 1970 that had the almost exact topology;1st stage FET npn cascode, followed by a pnp bjt cascode, the Sziklai pair driver is new however. Wish we could have had an amp like this in 1970. Engineers indeed have a unique set of binders on. Ray
