Hello,

after simulating and breadboarding the 6bB Filterstage of the 24dB "Diodenfilter" from Thomas Strauß in this threat: http://electro-music.com/forum/post-416539.html#416539 i used the experience to adapt it to other filter concepts because it fits very much in my desire: 1k,100k,1M and as less transistors as possible
