Hi folks, Has anyone ever replaced the PSU in a DEREP with a more modern equivalent? The PSU is an ASTEC but as usual doesn?t have any markings for ratings or pinouts. I found the tech ref online but for PSU problems it just says ?replace? as I?d expect. Test LEDs on the unit itself (and the fuses) show +5 and +12 at 2A. This one suffered a bad heat-based death at some point after the fan seized?
