![]() ![]() They are SO light weight unlike the 60lb Ampeg.QSC CX254 free download Professional audio systems service manuals and repai informationĮlectronics > Consumer electronics > Audio > Professional (I ask as I might want to buy one (New) for my bass stack. So anyone got any info on repair-ability for QSC amps? ![]() I would rather spend 200 on a repair than 600 on a new one. So my question is: Is it cost effective to repair the average QSC power amp with surface mount components in it or does one simply start replacing whole boards with bad components on them?Īll aforementioned brands are wonderful, but I do not want to sacrifice weight for repair-ability. I know you can replace what is burnt and keep the rest. Those are fixable with normal off the shelf parts. I own an Ampeg that has all through board and a Crown amp that is all through board. I could not locate parts that would fit so I had to make the parts fit by soldering wires to the board. I do repair amps part time and I have only worked on one mixer what was SMT. I popped the lids off of both of them and noticed they are ALL SMT!!!! I always knew QSC amps were light weight with SM power supplies (which I like) but I did not know they were all surface mount components. I removed them today and took them home with me after workshop to clean them out. We have never had any problems with them, however when I replaced a faulty mixer I noticed quite the dirt buildup in side and around the fans. They are contractor editions and they are about 8 or 9 years old. Ok, Our church has two QSC (CX 302, 502) power amplifiers. If you can handle that, then please help me make a decision. ![]() There will be no bashing of any of the brands mentioned. ![]()
