Not sure what it is about this thread, but why are we getting pointless reports to moderators? Spam bots perhaps? |

Hi JohnnyS, All, I have MS2661C with a defective power supply. I have replaced the AN8032 controller chip and a blown 10 ohm resistor. All other parts seem to check out ok so far. However, when powering up the supply with my current limiting bulb it blinks periodically. Currently waiting for a high power differential probe for some safe measurements with my scope. Have you had a chance to publish the re-engineered schematic of the power supply ? Any idea whether there is a chance to identify the main controller chip ( black square plastic package ) ? Thanks for any help ! |
