Hi Ale,
Have you seen JC’s buffer stuff? http://www.labjc.com/?p=2305
I’m sure it’s not too hard to convert the CF to a SF (cascoded fets of course).
I built one of my SF modules (Gary Pimm inspired) into a 9 pin socket so I could easily swap back and forth from the original PCC88.
best regards

Hi Tim, yes. Site crashed yesterday so apologies for late reply. I toyed with the servo idea for a CF, in fact your suggestion on the SLCF is quite a good candidate in my view. To resolve the DC offset issue, I was considering an input transformer.
A gyrator stage could be implemented with a dual balanced supply.
JC’s design is clever! Should look into it with a bit more detail. Trouble is that the JFET parts are not great for larger voltage swing, despite degeneration. Unfortunately there is no P type Valve 🙂
