hi I have print board which build in 1980's the capacitor is burned
when I plug the power, it labled as (+10, +35v) i think it is a
polarized 10uF, 35V but I am not sure, how long the capacitor last?
should I replace all of them on the board? (there are five of them
some labled as +1, 35v or 4.7uF 35V. thanks

Replace all your electrolytics...try and get a good brand name (Like
Panasonic) if you want to keep it running for a few more years...

Are they tantalum caps? If so, then replace all of them. Tantalums of
that era have a tendency to fail catastrophically. Aluminium
electrolytics of that age would be worth replacing as well.

thanks how can I tell it is tantalum caps? it is epxoy dipped
capacitors, it also have film type capacitor(square shape)and few
large alumnium can type capacitor should I repalce these too? thanks
