A forumfriend of mine, Bernd Jansson, is building a pair of watercooled Son of Zen with PP-coils. This is a pic from the initial testrun:
As he wants the input to be cap-free, DC-free and high-impedance, we discussed a buffer. The reason is that a S&B TVC will be used.
By adding two NJFs in a kind of currentgenerator-mode this could be solved in a very simple way. The prototype will probably look like this:
Theoretically this model looks good with for some reason indications of lower 3rd harmonic than the original.

This is an idea(same concept) of a Zen (SE) version. This one also for some reason indicates lower, high/odd-order harmonics than the original Zen.
