Default WTB: John Pomann's Active Crossover Kit

All,

I am embarking on another new project - as if I need ANOTHER project :^\ It would be really helpful if I could buy John Pomann's Active Crossover Kit - unfortunately it appears that he is not selling it anymore. If anyone has a gently used kit that is not being used, I am interested in buying it.

Edward

Here's an effort right here doing the same (actually better I would think) It seems more complicated but is the same basic idea, just more options if you want them andthere are lots of people here to help you.

On this new project, I am not building a standard crossover - so development of the circuit topology is required. So, I am looking for a 'one-stop' source for active circuit development. The Pomann kit came with a PS, breadboard, Opamps and lots of parts. For me to scrounge up an equivalent collection will require multiple vendors and dealing with minimum orders for a lot of the passive components :^\ So, I am definitely interested in a Pomann kit - or equivalent from someone else.

I have already joined the active circuit board group buy, that you suggested. I think that this board will have enough flexibility to implement the FINAL design of the circuit, I just need a good set-up for developing the design - hence the Pomann kit

Edward

you can get everything you need from www.mouser.com and htey have no minimum order. Resistors have a 10 piece minimum, but you'll want closr to that many if you are doing a 4th order filter. Use the values in the Acitve Filter Two manual at www.delta-audio.com for an easy starting point.
