Transformer design and switch mode power supply modification


I have a SMPS that is rated for 120Volts and it requires modification to operate on 240Volts.

I am aware the the Capacitor and varistor need replacement with higher voltages. The existing transformer may also need replacement so i will need a design made of the transformer and winding diagram.

I have photos which i can share. The circuit diagram is not available.

The cost of modifications needs to low approx 5-10USD
