EVERYTHING SYNTH
"For your consideration is a Yamaha EX-2. This polyphonic analog synthesizer is one of the rarest, most complex, and most expensive synthesizers ever built. Yamaha's flagship stage synthesizer/organ successor to the ultra rare Yamaha GX-1, this beautiful instrument packs all the sonic possibilities of a standard organ and polyphonic synthesizer into one gigantic and unique package. When released in 1977, the EX-2 had a $25,208 price tag. That's $96,227 today when adjusted for inflation, making it the fifth most expensive synth (in today's dollars) that Yamaha ever made, way more expensive than a CS-80 (which cost $6900 at that same time). Don't miss your chance to get this extremely rare and incredible-sounding synthesizer for much, much less!
"The KLM367 board had a battery leak ( very common ) and it was restored by vintage synth specialist at SDmachines in Miami. The old Rechargeable NiCad battery was removed and replaced with a lithium battery and diode combination that does not leak and is good for many years. Also, Two of the 74LS08 chips were replaced (these chips are known for dying in a polysix), along with resistor array R17 and some traces. This board came with the optional Korg Midi board, but was disabled because it was not functional, and returned to the original stock state. The board is in the machine and perhaps can be brought back to life by someone with the knowledge and necessary parts.

"The "Wobbulator" was one example of a recycled or salvaged piece of equipment put to creative use in the Radiophonic Workshop. The Wobbulator was in fact a oscillator (looking at archive pictures quite likely a Brüel & Kjær Beat Frequency Oscillator 1022 used by sound engineers to measure the acoustic properties of studios or by electrical engineers to test equipment.
