i received today an MS-20+delay Yellow Magic which was supposed to be a 4-pole Mission. I already own a Yellow Magic, so i can either ship it back, or try to exchange it here for another version.
I already have : Red Alert, Dual SVF, Yellow Magic (and Smr4 mkii on Ambika).
Lacking is one plastic locking ring nut on the audio input. Other than that, the unit seems fine.
