Well gang, here goes my first thread.
I have a pair of Klipsch ProMedia Ultra 2.0 speaker hooked to my laptop. Only bout 4 yo. I have moved several times these past two years. The puter is on a deep table with the speaker less than three feet apart and w/ the left sp near my seat.
Just this last week I came to realize that the right sp wasn't working. I checked all connections, (aber es war kaputt). I opened the right speaker and exposed the T amp there. One of the 470mfd caps had . The second 470 cap was deformed and not long for this world. The amp is on two boards ,one on top the other. A chore to separate. Only the two 470s were bad but since it was a chore to get in there and separate the boards and since the caps in this amp are Chinese it occurred to me that it might be best to change all electrolytics (10 caps all total).Thoughts ? Digikey has the panasonic caps needed.
The caps that blew for Panasonic is a higher voltage but I see no prob since the size is ok. If I do replace all the caps I thought to bump the voltage on the others as well since one value is only available at a higher voltage. The other concern in a question of what solder was used in the assembly. I use 63/37 out of habit. The boards are separated and the bad caps removed. I have been away from the bench for a number of years and the hands have turned to crap. I sure miss the Pace solder sucker used on my last job. Any and all comments gratefully accepted
