Hi
Always with the experimentation spirit, I decided to modify my microphone represented here:
http://www.groupdiy.com/index.php?topic=44096.msg648089#msg648089
Instead of a 2sk170, which has an input capacity of 30pf, I wanted to put a 2sk30ATM, which it seems to me very similar to the 2sk170 but with an input capacity of 8.5 pf.
I supposed that with less input capacity, I should get an higher level output signal, rather than with the 2sK170, ameliorating the S/N.
Perhaps my argue is wrong, and I ask you please to correct me.
however once I changed the FET, the microphone still working, but has an output level dramatically diminished.
I suppose there is something wrong, thus, in my assumption.
Can you help me please?
