“This unit is cosmetically pretty clean apart from some obvious nicks, dings, and chips that one would expect of a synthesizer of this age. Please check photos as I’ve tried to point out the main blemishes.
Unit has been thoroughly checked and is nearly 100% fully functional with some minor crackling of pots and switches here and there . . . this is a 46 year old synth after all. All knobs, switches work and feel solid and keyboard triggers reliably. The following are minor things I noticed while testing that should be mentioned . . .
White/pink noise switch can be a bit fiddly at times, but is mostly no problem.
Portamento can be a bit dodgy in terms of pitch tracking sometimes. . . again, mostly no issue.
The C# key in the middle octave sticks up slightly higher than adjacent keys. It triggers just fine and feels good to play, but is uneven compared to the rest of the keyboard. Please see photo.
I am not 100% sure if the VCF ADSR tab is working properly. When engaged, the ADSR does not effect it. The VCF ADSR pot will simply produce a positive offset to the cutoff frequency regardless of how the envelope is set. However, when both the VCF & VCA ADSR tabs are engaged, then the filter will respond to the envelope controls as you would expect. I believe this is the proper behavior considering there’s only a single envelope, but I’m not 100% certain. You’ve been informed.”
