I could speculate about this but I would think it needs an engineer to check it out. All these old organs have issues and they all need a few new bits to keep them working properly.

I am afraid I can't tell as I am here in the UK and I have no idea on the charges in your country. I can however go through the circuit and see what might need changing and then give you some advice you might be able to forward onto any local engineer who is prepared to look at it for you.
I'll let you know what I think once I have checked through the design.

Regards

Dave

Re: Technis SX-EX70M double notes ?

From what I can tell this organ has the plug in boards the same as the U60, U55 range of organs. These sit in a card frame to the rear of the keyboards. As such it is highly unlikely that it is repairable. I have done any number of these in the past and although they produce good sounds for their age the problems are spread over so many boards it might prove impossible for anyone without the necessary patience to deal with and It may prove just too expensive to repair.

If I come up with anything else in the next couple of days I'll add some notes here!
