Multivox MX-3000 polyphonic synthetizer

MX3000 partially working but that needs servicing. Check the video here or on Youtube to see what's working, it covers pretty much everything.
But basically this is the state:
Channel 1 / Bass: everything is working properly
Channel 2 / Polyphonic: 
All the preset sounds are working, as long as the "ensemble" fx and the "full rotor" fx. Filter, enveloppe and LFO mainly also. Velocity too.
What is not working correctly: all keys are working but a few notes (3 or 4) have a distorded sound. Lfo delay, glide and release are not working. 
Channel 3 / Mono: oscillator is not sounding. From what I can tell VCF, VCA, LFO and noise generator are working. 

In the mixer the Ch 2 direct is not working (but it's basically the Ch2 dry sound so it's probably nothing).
Overall condition is quite good: the panel is very clean. Case has some wear but still in good shape and complete with lid. Keyboard is not so great, lower part (bass part) keys are different from upper part, this is not original.

There may be some other minor things I forgot to mention but again check the video and you'll have a good idea of what you get. 
Since it definetly needs some servicing to be usuable I sell it for spare. No return that is.
Shipping worlwide, just ask for a quote.
