D-87 wind, wind noise.

Hi, i build new D-87 (the second). I build this model with a peluso capsule. I have a little problem.
Firstly i'd a big wind noise, i have cleaned all the circuit and reverse the capsule face connection.
Now, the cardioid position work fine, but i have the wind in omni and 8 position. i have sound but the wind to. :-[ :-[
Does anyone have a way to solve this problem please?
Thank
Marc

Could be the presence of moisture in the capsule ,put it somewhere warm for the day and try it again .A cold microphone used for vocals can also be problematic as condensation can cause disturbances in the insulation resistance of the capsule.Tube mics tend to run warm to the touch so its almost never an issue with them .

The capsule are brand new, it's a new build never use the microphone.

I would say the same thing, new capsule or not sounds like you have moisture trapped in the capsule. try drying it out.

Ok thank, how i can clean the capsule please?

You don't need to clean it ,you just need to put it in a warm place for a while and the moisture in behind the membrane will dissappear, the airing cupboard or hot press is perfect for this .

ok i will try, thank you.

Just wondering if anyone has tried  putting a capsule in a sealed jar for a couple days with a handful of "Do Not Eats", those little silica gel desiccant packages? Do Not Eats can be rejuvenated (dried) at 250F for a couple hours in the kitchen oven for reuse.

For that matter, maybe condenser mics could be stored in sealed jars with Do Not Eats, all fresh, dry and ready for use. Just thinking out loud.
