Default Hewlett Packard HP6228B regulated power supply

Hi,

Brought an HP6228B regulated power supply of off ebay, was assured it was working. Changed the voltage switch on the back to 230 volts as im in Spain. Plugged it in switched it on. It immediately sparked and started to smoke, so I switched it straight off. Anyone any ideas what might be happening?

Kiriakos,

Sorry what with the school holidays here have not had much time to look into this, however today I took out the master and slaves boards. On the slave board there is charring on to of the pins that plug into the mother board. Tracing these tracks they go to C6 however there appears to be no other charring.
