Bezimienny, the one knock on Jadis has been its reliability issues. Still, in my experience, my JOR and DA30 both proved to be flawless. Keeping my fingers crossed that the new DA60 I am about to get keeps this trend going for me.
If you find the hum is not able to be fixed by you (make sure it is not loose), I would contact Pierre Gabriel. He is a super nice guy, and very knowledgeable regarding Jadis. There's no reason the JOR should not be reliable for you once the tranny issue is taken care of, it's a very simplistic design.
