Eurorack 904-A VCF: buy the production files for DIY assembly for only 25 € (PayPal or Bank transfer)
The controlvoltage.org 904-A VCF is a DIY 14HP Eurorack-format clone of the legendary low pass filter from the Moog modular series, matching the original design and produced for personal use in traditional THT mounting and soldering process with discrete components. For sale are only the production files for the PCB (Altium / Gerber) and the frontplate (.fpd for Front Panel Express / Schaeffer AG) and the component list (Excel). Please note that this project needs some experience in calibration and transistors pair matching. Orders and inquiries: controlvoltage [at] bluewin [dot] ch
Alternate faceplates for Analogue Systems modules
Analogue Systems modules are great and the best way to get the genuine EMS sound. Unfortunately the faceplates are rather cheap, comparing to the overall excellent quality of the Asys modules. In particular the silkscreen printing is very poor and comes off easily, so i decided to redesign some Asys faceplates (RS-95-E, RS-500-E and RS-510-E) with infilled engraved scales and a reduced thickness of 1.5 mm matching the Eurorack standards. They were designed for personal use but are also available for purchase in .fpd format (Front Panel Express / Schaeffer AG). Currently available is the alternate faceplate for the RS-510-E trapezoid generator, sale price is 15 Euro (.fpd file only, PayPal). Orders and inquiries: controlvoltage [at] bluewin [dot] ch
TheWarp analogue synthesizer (ARP 2600 clone / reinterpretation): the complete production files are available for sale (price on demand)
TheWarp is a modern hardware reinterpretation of the legendary ARP 2600 semimodular synthesizer. Developed in 2014 by swiss electronic engineer and former Gotthard keyboardist Neil Otupacca with my consultancy, it is based on the original schematics and interely built with analogue components in traditional THT mounting and soldering process. Redesigned to fit within the standard 19" rack size, the actual instrument retains the graphic design, the size of the sections and feel of the original. Originally planned for series production with an estimated sale price around 3000 €, the project was abandoned because the minimum expected number of 50 pre-orders wasn't reached, but i believe it ought to be launched on the market, so the production files are available for sale to anyone interested to manufacture and sell it under his name / brand. Please go www.controlvoltage.org/thewarpsynth for further details.
