Roman Sowa’s Synthpages
I’ve referenced Roman Sowa previously in the AD633 Ring modulator post however I’ve never posted about his past work. To start with, Roman has incredibly detailed build pages on his DIY analog synth projects here. If you dig in and check out the details on his modular build he includes photos, schematics, and technical details that are more than sufficient to guide you in your own build but not overly verbose and distracting. Take a look at his extraordinary hand-made modular.
