 Building the 2720 series modular.The line above is not a link to the article, but one for posting a reply.
This article by John Simonton describes the assembly of the predecessor to the 2720R modular synthesizer offered as a kit package or individual modules through PAiA catalogs in the 1970s and 1980s. The 2720R had an actual AGO style keyboard and updated electronics (2720-8 sample/hold and voltage divider boards) and with options for a 2720-9 glide retro-fit board/control. This DIY magazine artilce project included modules and circuit-board-kits for the following items: 2720-1 VCA 2720-2 VCO 2720-3B Bandpass VCF 2720-3L Lowpass VCF 2720-4 Envelope (Function) Generator 2720-5 Control Oscillator (LFO)/Noise Source 2720-6 controller Vinyl Strip 2720-6 controller cv Sample/Hold 2720-7 Power Supply Attachment: _________________ Scott Lee scott@paia.com |
