Re: Trying to save a 576


Working in the low voltage section of the 576. This is an older low voltage board all gold traces. The power supply keeps resetting itself. I was monitoring the -75 volt rail yesterday and it was rock solid for about 20 minutes. Then the power supply starts to rise to 0. Then it totally collapses and starts oscillating. And as it is doing that all the relays in the unit start to chatter and stutter. Any one have any ideas what might cause this or am I in for a hunt?
