Hi all.
I have an Aethra ADSL tester. Currently it runs with a battery but I would like to use it with an external power supply. Kinda I'm looking for identify two poles for the power supply. There are 4 pins on the power-in DIN-type connector.
Looking the PCB some doubt are arisen about the components which I highlighted with a pink circles. I think that the small component with over the letter P looks like a fuse, and the qaudripole in bottom right corner seems a transformer or a filter... but I don't find any information about that TSOP labeld D236.
Anyway a similar schematics seems like this:
Maybe watching the PCB, you can help me to find two poles or maybe you already have a similar power supply for a similar instrument or to help me about those strange components.
Regards
Ciro
