i dont know yor circuit diagrams...

thats why i asked that question..
as a 9mm pitch is not often used... :-)

so as it's just a "little" critical....  why don't you use a SMD inductor?

and a pre-amp input should be high resistance( >1 MOhm) ..... means.. nearly no current

or am i wrong????

Originally it was a 33mH, shielded - hard to find in SMD at a reasonable price
At the last moment the value changed to 3,3mH .... and PCB was made :-)
Yua are not wrong  Smile
It takes only a little current, but the supply voltage can be as low as 3.3v
Minimum voltage of the op-amp is 2.7V and there is loss in the cable and two inductors.
