![]() 10V apart is normal Pin 6 is strange since the DA (Digital Analogue) needs more than. Now my sanity check to see if I understood the circuit perfectly: Pin 3 and Pin 1 check since they are in the same side of the transformer, the primary side, so their voltage being. So with a lead on a GND pad I made some measurements and: Pin 6 goes to a pair of Caps in parallel. ![]() So using the schematics available online I try to do some measurements: So basically on T1: So I though of trying to know the rate of the transformer and try to get a compatible one. It also helps that a lot of different markings are available for the same part: I could desolder it and measure his inductance but I don't have a LCR meter available. I'm trying to help someone repair a Gameboy Advance that have a Custom Winding SMD Transformer broken (T1): Easier said that done since this part it looks like it is custom made and all the search I've done online regarding the printing on it return into nothing. ![]() ![]() Heck, this thing is making me question a lot of things. ![]()
