Hi,
I sell my Oakley Filtrex2 Cv filter PCB fully assembled with high quality parts:
http://www.oakleysound.com/filtrex.htm
there is only one pot that sometime “crack” when you turn it (the main out volume, by the way it’s a pot you set one time then don’t tweak so much), all other things work fine. It’s sound really smooth, with analog LFO and EG.
It’s can serve as a great line/Instrument/dynamic mic preamp
It’s a discontinued product, so it’s by the way a very rare gear.
I will send with it the panel I’ve done, but it’s DIY one, so probably you will prefer to make another one. You have to find a casing by yourself, so it’s rather for DIY geeks 
It’s powered by an high quality transformer, I can rip it to avoid to pay to much shipping charge.
The original schematic will be mailed to the buyer.
Price start at 120E, it’s less than the price of the original parts, hope you will want to add some more buck for my own work on it ;-)…make an offer!
all my best..
