Klangbau Köln Twin Peak Filter

interested in purchasing one.... if anyone has one willing to let go, please let me know... and thanks

I will never ever sell mine but i suggsst to email the maker and ask! he explained everything super clearly and offered options (such as panel type, etc.). super easy purchase experience.

If he isnt alive and making them, who else is in charge of taking orders? any help would be great

did willi die? if so, that is sad. i was not aware. i bought a Twin Peak Resonator from him last August.
