well
one question about the vintage phase shifter
(with two similar resistors at the -input and the feedback and the RC to the ground and to +input)

what is the bandwidth of this???
it is certainly not the ideal one
is the magnitude characteristic bordered by vales of R AND C or only by opamp????

cheers
