OB SEM 24db filter mod?

[Rob01]

Ok, from what i can see in the schematics provided by Synthfool, it LOOKS
like the filter in the unit is only 12db, 2pole.. Could i just replicate
the stages, chain the other two new stages to the output of the existing 2,
and come up with a 24db filter?? Then, i could move the points that the
bandpass output is being taken from, and I SHOULD be able to get a 24db SEM
filter, right? just checking. If i could do that i think it would be a
pretty nifty mod to the SEM and one that you could switch out a will...
Kevin, have you ever done this, chained a couple of these units filters??
and if you did, did it work??


Another thing: what is the input to the voltage regulator on the SEM?? I
only see+-15 and +- 18, which is the input off of the bridge rectifier?
