Yeah, i fixed it
It wasn´t a fuse but a faulty 7805 (+5V voltage regulator chip). Cost about 1€ in the local electronics shop and a couple of hours troulbeshooting and welding work and it´s up and running again. Some of the keys are a bit crappy though (you have to hit them very hard to make them work). I tried cleaning them and correcting some bend key contacts but that only worked on some of the keys but hey; MIDI works and i cost me 1€ i spare parts (actually the bus ticket to the electronics shop was more expensive) so who gives a shit. Sounds great too
There´s some great sounds on it that my friend i got it from programmed. I´m impressed that the memory still is intact since it has been in his attic for years. Mayby i should do a backup if he like to use some of them again
