|A big problem for the
settling node method, small settling signals
are overrided by the 300mV clamping voltage from the
Schottky diodes. Unfortunately there are not many diodes available
with a lower voltage.
I thought much about many solutions, I didn't see any solution without switching.
Some offer RF diodes with a low VF voltage and low capacitances.
Tube diodes could be also a choice. let's try these old parts first. Sometimes it's a good idea start on the beginning than you'll understand the new days.

Radiated free electrons from the glowing cathode cause an unwanted
current, if not blocked by a neagitve grid voltage of approxiamtely
-1V. Need a switch to avoid this inrush-current, grid switch.
Unfortunately I don't see a change to work with tubes, but it was a nice experiment having some fun. I am still waiting for special diodes.
