A friend of mine build me a tube version.
the sound i got was a little sharp so we began thinking to modify the cartridge for less mechanical resonance.
i show a picture later. Unfortunately I do not have much time for DIY now.
I used a Baxandell pair as constant current source. Yes, I know that this circuit is not ideal, when 38mA is around. It plays though and I have made another circuit that seems to be better.
