Vintage EML200 Blue Synth

via this auction
"This is a very rare collectible synth. Quite unusual and should reside in a museum or vintage synth collection. Only a few hundred EML200's were made. This unit requires a tube (easily accessed in the rear), and is sold as is. This EML200 synthesizer is vintage. It's a hybrid cross: a synth with cable patches (not included) much like an ARP 2600 or Moog, and a piece of test equipment . The sound possibilities are truly amazing. The tone of this EML200 is very different from that of any other synth made. Vintage 1970s. Even has a built-in spring reverb. More valuable than the silver model. It's a great stand alone unit- or patch your other equipment through it. It looks cool just sitting there! Mic preamp for external sounds.
