[EC4TR Luis]

Hi all
One guy, is selling this filter,
http://www.dci.ca/?Section=Products&SubSection=Amateur
I am thinking in the possibility of using it for desensing problem with 
FO-29.
I`m pretty sure it would work fine, but the question is, would it pass 
dc power for feeding the preamp?
Somebody knows it?
I asked them via email, but not answer.
