As I said I have no info on this machine but when I have had the PCB in for repair the one shown on the RH side of the photo it looks like a timer card and although my first thought was the box on the LH side of the photo was a capacitor bank for a thyristor controller after a second look I am sure its a large resistor bank for a resistor controller. Mike does the box on the LH side contain what looks like large springs?
