UcD 180 Supply ST problem
I have two separate Ucd180 mono blocks that has produced music two years now witout any problems. But now, one of my mono blocks is not working. I have figured that it is the UcD 180 Supply ST that is the problem. I can measure +/-48V AC from the transformer to the supply, but I can only measure 0V (actually +3V and -0V) DC on the outputs from the supply.
Can anyone give me some guidance on how to troubleshoot? |
