"Vintage Oberheim TVS-1A Two-Voice Analog Synthesizer in 100% Working Condition. Very well cared for with all original knobs with caps, all LEDs working, no sticky or dead keys, no dirty pots, no hum or crackling. There is one issue with the high "B" key being a bit higher than the row (please see pic). It does not affect function or playability. This TVS-1A will be meticulously packed with only new bubble-wrap in the first new box. Then, more new bubble-wrap inside the second new box. A 37"x30"x18" double-walled box weighing in at 51 lbs. 4 oz. Includes two power cables, copy of the manual and schematics. Capable of deep analog saturation without losing clarity. The incredible sound one expects from vintage Oberheim SEM modules. In 1975, Oberheim created their first compact, programmable and polyphonic synthesizer by coupling two SEM modules to a 37-note keyboard and a simple analog sequencer. This was what became the Two Voice. Oberheim achieved a polyphonic sound not yet seen at the time by hard-wiring the two monophonic SEMs into the compact keyboard design. In 1976 Oberheim came out with another module, the Polyphonic Synthesizer Programmer. This could memorize the control voltages of many parameters for up to eight SEM modules. When these were added to the Two Voice in the form of the Mini-Sequencer, Oberheim finally had one of the earliest programmable and polyphonic instruments. Each voice has its own filter. The filter is unique and like no other, and apparently cannot be reproduced even by its own creator. The 8-step analog sequencer controls each voice/module independently allowing two independent sequences to be run simultaneously if desired."
