"Vintage 1970's EMU (Eμ) SYSTEMS MODULAR Synthesizer parts. Designed by Dave Rossum and Scott Wedge and made in Santa Cruz, California between 1972-1980. Fewer than 100 Eμ synths were ever made and most are in University music departments, museums, or in the hands of well-known musicians and composers. This collection of parts includes:
- over 120 NOS printed circuit boards. These are all 1970's blue Eμ PCBs and all have hand-inscribed serial numbers
- a recently serviced original power supply/keyboard output module that works well and has faceplate, working on/off lighted switch and new 3-prong socket cord
- an extremely rare walnut (narrow) top cabinet with serial number 011. I'm told 011 may signify number 1 since the likelihood that 11 were built is slim. Made by David Rossum's brother, who built Eμ's early cabinets
- 3 original untested Eμ modules with faceplates and knobs. They are a Dual Transient Generator, a Triple Latch and a Memory module- 100's of pages of copied documentation including schematics, parts lists, and technical info. I'll also send the buyer several pdf. files with the Operating Manual, catalogs and other docs
- 7 faceplates (Quad VCA, Sawtooth/Pulse VCO, Noise Source, Programmer and Tape Interface) and 19 rear panel brackets/thumbscrews
This would make an amazing project for the right person. Most of the electronics components used on the originals are still available today or can be tracked down by the diligent. Many parts (like certain Bourns pots or Switchcraft switches) haven't changed much in 35 years. The 4 included Eμ modules and cabinet give the retro-builder original reference examples, making it possible to match their reconstructions perfectly. The parts included in this sale could produce a large double cabinet Eμ system..."
