|19-08-2009||I found a picture of the board online. This board is selling for $180, but the same caps that were bulging on mine also look suspect on this one. I wonder if someone can look at this and give me an opinion on these capacitors. They're the two large ones,|
|19-08-2009||Having seen it before, I can tell you that they are OK and more likely the same with the capacitors in question on your board.
The subject of "bulging capacitors" is indeed valid and rather a common failure however, it is mainly observed with l|

I pulled out two transistors from an electronic balance which I think are defective but having trouble identifying their correct specifications. The markings are N1117 and N1212. In my opinion the full part number should be 2N1117 and 2N1212 (plea|
