[QUOTE="Lasherž, post: 8704188, member: 679555"] Yeah, honestly if you can say with decent certainty that replacing the caps would work then it's always worth swapping them. With amplifiers the only difficult thing about swapping caps is that they absorb a lot of heat before the solder melts because they've got beefy ground plains. At the very least you'll want a ceramic element soldering iron with an adjustable heat setting, otherwise you'll just heat up the board without melting the solder trying to get them off. The caps themselves are going to be cheap and if you can get new ones from a good brand they'll last far longer than the old ones. There are many caps that have 25 year lifespans in typical use cases. [/QUOTE]
