Octave Plateau Cat Synthesizer SRM II Vintage Analog (NOS) SN G1218 w/ Original Box & Brochures

via this auction

"We have been fortunate enough to acquire some New Old Stock (NOS) Cat SRM II synthesizers from Octave Plateau’s last production run in 1981. These units have never been used and were safely kept in storage since the day they were manufactured. If you’re an analog synth aficionado, here's your opportunity to own an authentic piece of electronic music history.

The Cat SRM II was manufactured in 1980 – 81 and is the best and final model of the Cat synthesizer series from the mid-1970s, which included the original Cat and Cat SRM. We calibrated and thoroughly tested these units to assure everything works as designed. The switches, pots keyboard contacts, buss bar and electronic circuits have all been cleaned and checked. We also replaced the original press-wood sides with high-quality genuine walnut wood sides and replaced critical calibration single-turn trimmers with high-precision multi- turn trimmers for greater stability. Also included is a foot switch that plugs into the back of the synthesizer (see photo) and turns on the glide function when the switch is pressed, allowing a smooth glide between notes only when desired.


Monophonic/duophonic keyboard plays two notes with memory function on second note.
Digital keyboard with single contact per key (more reliable than the dual-contact analog keyboard used on previous Cat models and most other analog synthesizers of the day).
Dual VCOs (CEM3340) with oscillator sync and mixable waveforms for complex tones.
Sub octaves on both VCOs for full, deep bass sounds.
Four-pole LPF (SSM2044) with adjustable keyboard tracking.
Versatile modulation system to create a wide variety of sounds.
LFO (with variable delay on sine output), S&H and dual envelope generators.
White noise generator.
Extensive expansion jacks on rear panel.
Although this unit has never been used, there may be some minor cosmetic imperfections, which is how it left the factory. Please refer to the photos for cosmetic details."
