TB303 Filter Clone

Hi,

I am really interested in building a TB303 filter clone for my modular. I don't particularly want to build an x0xb0x, only the filter.

Do any PCB layouts or schematics for a TB303 filter module exist?

Any help would be greatly appreciated.

Thanks,
OW.

There's the Oakley ladder filter by Tony Allgood.

Component changes are marked with a * on the schematic for the 303 version.

And a schematic of the original one :

Thank you!

Do you know if a PCB layout for the filter exists?
