Powertran Transcendent Polysynth

via this auction

"This analog monophonic synthesizer was designed in the UK in 1978 by Tim Orr of EMS and made by Powertran, Hampshire in the early 1980s, either as a fully built synth or as a self assembly kit through the publication Electronics Today International. The synthesizer produces a distinctive sound and is believed to have been used by Thomas Dolby, New Order, Joy Division. The Transcendent seems to be quite rare and collectable now.

The synth features CEM chips (as used in Prophet 5, Pro-1, Korg polysynths etc) and has been described as "the kit-builder's Jupiter 8 without the memories".
