I do not find the black and white from Sonal, he posted only the 1 pair power mosfet type...
Greetings🙂

Years ago(1990?) in the Elektor cmos preamplifier used cmos and op amp in input and out, as source switches.
I will try to find the boards.

I found it!

No, I never made an FH11. Closest is CFH9 though - listening to it now. Very nice.

I used a cmos cd4016 and/ or cd4066 with great success. You can't hear them in the circuit at 18v and 47k 47pf loading. CD4052 4*2 makes a great analog selector.
newer chips provide better resistance but it's moot.
I still have the 1024 step attenuator I made for fading tape recordings in and out.
Their only practical limitation is the rail to rail maximum input signal
