Got a pair of Yamaha NS-15 speakers for 15 bucks at a garage sale. They've seen some years but the cones are in great shape (polystyrene of all things), the boxes are still holding together and overall are in good shape. Bad news is one of them is dead, the seller says it went out just after moving but had no clue what the problem was, opened it up to find a single wire had broken free of its solder. The wire goes from the red (+) speaker wire terminal to a grey cylinder and from there to the treble control. The cylinder is labled with "Nichicon 160v 2.5m". I'm wondering if I can just desolder the thing and resolder it or if this is something a pro should handle seeing as my soldering skills suck. Any ideas?

The cylinder sounds like an electrolytic capacitor. If a loose wire is the only problem, should be really easy just to resolder it, no pro needed. It would be really hard to damage the capacitor, but even if you did those things cost like 20 cents.

what about the flux capacitator? one mistake and that thing might become incapable of time travel

Resoldering didn't fix the problem, tried twice, still totally dead. Thinking the capacitor is dead or some other component is fried. Whenever I get around to it I'll take it into a shop.

Hmm, with speakers that old, the electrolytics may have dried out.

Seconded - old caps can often be dodgy. Replace that sucker with one of equal or near-equal value.

OK. So I'm assuming "160v 2.5m" was Nichicon was of saying it was 160 Volts DC at 2.5 milliamps, sound right? Also do I need to buy the same type or will anything near the same rating due? I've noticed the size of these things have shrunk to a fraction of the originals...

On a capacitor "2.5m" would be 2.5mF, not mA (you might come across a replacement labelled in uF, in which case it's 2500uF). As long as you're fairly near to the rating of the old one you should be fine.
