[QUOTE="kubusi, post: 798581, member: 19010"] From the information you have given and the measurements made the 50-0-50 is obviously the secondary with a centre tap so with 2 nice sized diodes connected to the red wires you will get a nominal 50 volt input to the filter/smoothing caps and take the negative from the blue wire, if you ignore to blue centre tap and connect a bridge rectifier to the red wires you will get a nominal 100v. On the primary side the 0v is used with either the 220 or 240 volt connected to the mains input, however if your mains supply is 230 or 250 volts instead of using the 0v connection you use the 10 volt input wire. If you use an ohmmeter and measure the resistance between the 0v and the 10v you will find the resistance very low as it only consists of a few extra turns of wire on the transformer. The 2 amps I would guess is the current available across the 50-0-50 ie at 100volts so at 50 volts as mentioned above you would be able to pull 4 amps from the transformer. Could be used for a nice solid state amplifier. [/QUOTE]
