skittlesRgood Posted October 9, 2010 Report Share Posted October 9, 2010 oh, i see. i figured it would just be adding solder. i have an amp i working on now that definitely had some crappy solder joints on the output fets.

That is what he told me when he repaired my old amps that ran vertical mosfets. Not sure if he adds more too it or not however, but Ive talked to him a good bit about amps and amp repair.

STEvil Posted October 10, 2010 Report Share Posted October 10, 2010 Thats awefuly expensive to fix a powerbass amplifier. My spl dynamic 3000s where only $300 to rebuild the powersupply @ db-r Db-R solders the mosfet legs from both the bottom side and top side of the pcb to stiffen them up as much as possible. The weak solder joints from the factory is what allows the mosfet legs to stress and break, keeping them flexible while fixing the amp will result in the same problem. solder type plays a huge role as well. Many "new" solder types are lead free and this causes poor joints which crack easily.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.
