I've played a bit with the Wenzel circuits and they can provide truly
outstanding damping, my best was 80dB using a HP VHF transister I can't
remember the number of.
And yes, they are very sensitive to just about everything, in particular
But getting at good solid 30+dB damping is not _that_ hard, in particular
for very low-current constant loads, such as X-tal oscillators.
