DIY dual filter for ARP synths

[Rob01]

The schematics are currently only in GIF format (average quality),
and the rest is Postscript. I hope to be able to convert the docs
into PDF format as soon as I get access to Adobe Acrobat.

If you have any questions, please do let me know.

Hey!
	Very good idea! i have always entertained the idea of converting the
filter of my Odyssey II because it really doesnt have the bite i look for
in a filter..Neway, i looked at your schemes at the link you provided, i
understand the schemes, but, i need to ask you, (1) will i have to make an
entirely NEW pcb for your design, or can i retrofit your mods to the
original filter module?AND (2) if i do have to completely replace the
entire filter/pcb, do you have the artwork, and if you do, what format is
it in? Thanx, personally, i would LUV to betatest your little bit of engr.
in my Odyssey II, and if i experience any probs, perhaps offer a few
solutions, but, offhand, your schemes look pretty sensible! 

well, lemme know whats the best way to go about this, and ill give it a
try!
