Before I ask, I know the risks involved in opening
When you heared or noticed any burnout components,most probably from the regulators/rectifiers/IC's/ voltage limiting dides/ etc,it means you're having a problem on your driver up main outputsection in your circuits ,you have to check steps by step,n most cases,like this HIGH POWER AMPLIFEIRs,its using a high wattage transistor/Mosfet particularly,
After replacing some faulty components,,Please,.kindly .do not connect immediately your expenssive speaker's,if you've 8ohms /50-100W dummyload parallel with your( ohmmeter on AC set), to monitor the ac abrupt dumping factor on the main output,
When you noticed your amplifier is having a problem like poping sound/motorboating sounds/burned components and smell/trembling with low freq sound and etc,
Do not connect your speaker,specially HIGH POWERED OUTDOOR AMPLIFIERS just to avoid any damage or create fire, and extend some components damage on the circuits,
In deep repairing and troubleshooting in any electronic equipments, it needs complete diagnostic tools/schematics/techniques,...experience and observation sometimes is required,
IF YOU DONT HAVE IT,ITS BETTER TO BRING YOUR AMPLIFIER IN A SERVICE SHOP,
My friend,thanks and good luck,.
