As the C128D power supply is based on mains transformer, first thing you need to replace is said mains transformer. It's probably easier to just remove the whole original power supply and replace it with some small industrial 5VDC SMPS and 9V transformer (assuming that nothing depends on the frequency of the 9VAC input, which from looking at service manual seems to be the case).
