Hi Razvan,

I don't have a schematic, but mine has an Artesyn NFN40-7608. The datasheet is here.


Is the standby light on, or do you get nothing?

Tom

Hey everyone,

Is there any information out there on the power supply used in these
units? Mine appears to have died (I can't measure any output), and I
can't find the schematic in the CLIP files.

The full part number of the PSU seems to be JW 1287, JW being the
manufacturer.

This isn't the first time it failed. Many years ago a resistor went
open, but I don't remember how I troubleshooted that, and I didn't
take any notes...

Cheers,
Razvan
