I have a Sounder Power System Blue Series 20M. I blew a transistor, capacitor, and a resistor while operating my trains. I know the values of the transistor and the cap, but when the resistor blew it took whith it the colours of the rings, so I can't tell what the value of the resistor is. It's the resistor coming from the speed control pot to the direction switch. If anyone out there has one of these power supplies, could you open yours up and look to see what the value of the resistor is.
