Hello
It was little long time but finally i did it :)
This upper keyboard is old one from SIDO v2. Current is 2.2bcv. Lower keyboard thats of course DAX control panel. As you can see DAX works on two pcs 7805 in different sizes... anyway before them ive installed DC/DC converter - thats for possibility to use any power supply (with higher voltage than 8V, may be 9V DC or AC - doesnt matter).
Cheers
