images via this auction via Tec."For auction worldwide a pair of Oberheim SEMs in a solid oak box draw with modularised jack connections to the board points.
Powered by an original Four voice supply,set for 230V use.
Many of the 1/4" jacks are normalised such that the MASTER CV will input on all four VCOs and also the MASTER GATE will input both modules.Inserting to individual jacks will break the master connection to that part.
Jacks in for VCO1:CV1 CV2 SYNC ,VCO2: CV1 CV2 SYNC, VCF:CV1 CV2 ,VCO1 : MOD, VCO2: MOD ,VCF:EXT INPUT 1 & 2 ,VCF MOD ,ENV1 GATE,ENV2 GATE and VCA CV.
Jacks out for VCO1 SYNC OUT,VCO2 SYNC OUT,VCO1 SAW PULSE,VCO2 SAW PULSE,VCF HP BP LP,ENV 1 OUT,ENV 2 OUT,VCA OUT.
28 jacks.....per SEM.56 total.The four VCF CVs have attenuation pots with the same production grey knobs.
The jacks are seated on 3mm Perspex acrylic with card paper backing for decals.It would not be hard to replace if you have an aversion to yellow.
The SEMs are in good cosmetic condition...unfortunately one dual pot cap is missing on the right hand module.
I built these into the box before i started on my modular build and as that took over this piece was put in storage for some years.I brought it out to sell and we must consider that the modules are 30 years old.I've tested both modules by the master cv/gate and both VCOs are outputting saws/pulses/syncs.
Some pots could certainly do with a clean.Filter outputs and envelopes are working.I have not checked the alternate inputs but i don't see why they shouldn't be working.
The main niggle is the right hand LFO isn't working(probably a dead 741 or the jfet)but since it was a simple device anyrate and i had plenty of better LFOs offboard i never repaired it."
