	Yes. These people do. Give them a ring. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Can you post high resolution pictures of both sides of the power supply PCB? How old is the unit? Do any of the electrolytic capacitors look "distressed" (swollen, lifting off the PCB)? This is the most common cause of failure on old PSUs. Can you see any evidence of overheated components: blackened burned components; darkened area of PCB etc. Examine both sides of the PCB carefully even if there are no components on the bottom. In desperation, if it's 5 and 12 volts, could you replace the whole PSU with a PC PSU? __________________ We are alone in the universe, or, we are not. Either way it's incredible... Adapted from R.
