I am trying to repair a combination electronic transformer/dimmer. It converts mains in to 12V at about 80W to supply a floor lamp with halogen lamps, it has an integral dimmer. The two suspect components could be transistors, they are TO220 packages and have printed on them the letters ST inside a sort or angled square with the numbers 9622. Under this is the word Malaysia and under this is RELCO5. Anyone know where I can find info on these or if you recognise them what equivalent I could use. Thanks.
