Hi, first timer here. I have an early 90's Johannuss Opus 275 which has done serviceable job for the last few years but now all the stops cut out within about 90 seconds. Switch it off a couple of minutes and it will work again for 90 secs. It seems to be something is warming up and cutting out. Does anyone have any ideas if this is an easy fix.
This organ does have midi, does anyone think The midi output could work with this fault?
