Update on my last post.
It is alive again. Today after work I started measuring again. I thought it was a short on the ANAIN board. Because the 3.3 volt was present on the connector from the psu when disconnected from the board, but it went 1 volt once connected...
Today i measured on other connectors from the psu where the 3.3 is also present and there was no problem there...So it had to be on the power supply itself. After checking i found a burned trace. So it still had some connection, enough to measure the right voltage without load connected. But with load the voltage dropped. Very tricky![Smile](https://music-electronics-forum.com/core/images/smilies/smile.png)
So happy days here, the unit iis working. Now I better order the complete list of caps and do the recapping job.
cheers,
Maurice
