Hello All,
I was recently given an old Johannus Opus 1400 by a school. It had been badly vandalised and was no longer any use to the school. A few years back, somebody unscrewed the back and stole most of the internal speakers. In order to get at them, the thief cut all the wires connected to the racks of main circuit boards. I'd like to get it going again, but there are an awful lot of wires that need to be reconnected.
Having no experience with electronic organs, my first problem is not knowing what it's supposed to look like back there! For all I know, more is missing than just the speakers. So any schematics or photos anyone might have of a complete Opus 1400 (or similar) would be greatly appreciated. I have contacted Johannus and asked for information, but apparently the person I need is on holiday, and won't be back for some time.
And one technical point: I can match up pretty much all the bundles of cut wires from the circuit board racks to the inside of the organ. However, in many of these bundles there are (for example) two black wires, or 10 red/white striped wires. So in these cases, when there are multiple wires of the same colour, can I assume that it does not matter which connects to which?
Many thanks for any help
