I bought a Crumar Stratus 3 weeks ago, and the Price was pretty cheap (200€ with shipping included). It Works perfectly, except that depending on the voice I'm playing, some keys are not playing properly. For example: for the organ everything works except the G4, but for the synth only 7 Keys/Octave work….
The sound i get is great, and I really need to fix this, cannot wait to have it on 100% working
I tried to dissamble it, and everything is original, and never touched, (18 CEM chips included).
For the issue, I only can thing is somehing worng with some TDA's that are not getting the key signal out, and now comes my question

How can I acces to them???? the are over the keyboard, but really cannot move it out, does anyboday knows how can I do it? Did somebody have the same problem before?
Thanks! cannot wait for yout answers

Cheers!
