PCBs are in stock and available to purchase for System X Filter and Continuum Phase Shifter. Also, a handful of System X Envelope PCB/4HP panel bundles are available. I’ll be updating the Synth DIY page soon, but in the meantime, please email me at frequencycentral@yahoo.com to reserve yours.
Pre-orders
The rest of my projects will soon be available again as professionally fabricated, silkscreened and solder-masked PCBs, together with accompanying professionally fabricated panels. If you would like to pre-order any of these projects please email me at:
pre-order@frequencycentral.co.uk
Subject: The name of the project you would like to pre-order from the list below (eg Waverider Digital VCO).
Email content: Please just state either PCBs or panels (or both), and how many of each.
If you want to pre-order different projects, please send multiple emails with different subjects.
I will use pre-order emails to create a spreadsheet (on a first come first served basis). I will not be replying to your email except to alert you to the future availability of the project. When you pre-order, no money changes hands until the project is available.
Legacy Projects
For those of you who already have PCBs that you are yet to build, here’s the build documents:
Bullwhip Filter
Roland 100M VCO
Vogue VCF/VCA
