Korg LAMBDA ES-50 Vintage Analog Polyphonic Synth w/ Orig Box SN 230784
via this auction
"The unit appears to be working reasonably well, I noticed 3F and 3D# keys seem to be not responding, as well as PERCUSSIVE and ENSEMBLE buttons having bad response/contacts even though the function itself is fine. There are also slight bad contacts on some of the switches and scratch noise on the knobs, which could do with some servicing/adjustment.
Otherwise all the preset sounds working fine as well as all other switches and knobs working well to the best of my knowledge."
