ST-Modular EFI filter

This is a multimode filter.

It's loosely based on the Korg MS 20..

I started of with this module as it has a very low part count so should be a easy build.

Plus I like small filters.

The world needs more 6hp filters

The filter has both high pass & low pass modes.

I like to start with the ICs

LM 13700M

these are pretty common op-amps

 The diodes aren't the exact ones from the BOM.

I had lots of spares of these from my NLC builds.

 

 

The parts are all 0603 SMD

Many thanks to Ed from Elk Elektronics for the kits and help in trouble shooting the build.

nice ... almost there

finally we are there
