“Nice cosmetic shape overall, a few light marks nothing major, but had the common battery leak issue when I got it. Mostly works now after some repairs done, but has some issues still left that will need repair, listed in detail below what all works and what doesnt to the best of my ability, tho I am no expert on these. The batt board was cleaned up and traces repaired and 4 chips replaced, which fixed many of the common issues from the battery leak, but a few problems remain. I do not know if any remaining problems are due to more probs on the battery board or something else, so it may need a new klm367a batt board, or maybe not, might be a prob on a different board or something…or all the above, dont know not an expert. A new battery was not installed, so there is no patch program memory, just random patches still in it. You can get a new klm367 board for about $200ish from a nice german seller synthronics.de who I think sells them on ebay and said it would take about 3-5 days via express shipping to usa, if you cant find the link ask me. I was thinking of getting one from him but just dont have the time anymore, and figured maybe an expert on these would be able to fix the remaining probs without needing a new 367 board. So this is sold as is, partially working, for repair, no returns.

Here is the list of what works and what doesnt, to the best of my abilities:

WORKS:

all keys work perfect, just cleaned too
all 6 oscillators including the sub osc settings
the VCO section 3 waves for saw, pw, pwm, speed
sub osc settings
tuning knob
volume knob and output settings
the mod and bend wheels
all effects in the effects section
keyboard tracking
the arpeggiator
the key modes (poly, unison, chord, hold)
All the audio outputs and jacks
All buttons and switches for banks and program #’s
(a couple of the program # buttons you have to press a little hard but all work) ”
