[QUOTE="amprepairman, post: 6659992, member: 618082"] I have but never actually seen one that was"blown up"just silly little problems..I had a guy bring me one( a brutus series) about 2 weeks ago and it had been running so hot that the power supply transformer had started to fall out of it..(He had it mounted in a boat if that matters)....anyway I just resoldered it and it ran fine...I was looking for his ticket to get the specs off of it from when I tested it but my self appointed daughter/secretary must have filed it as complete and I have no idea what happens to stuff once it leaves the general area around my bench.Generally Class D amps have higher distortion figures than a class AB to start with but I know this amp couldnt have been far from normal or at least what I was expecting to see or I would have remembered it and I'd still be talking bad about it to someone... Usually class D amps are pretty reliable reguarless of the manufacturer..they are efficient and run cooler than comp. AB amps and seem to have more failures due to breakage(literally) of parts due to shock or vibration and solder issues...as compared to actually blowing up..and if one does actually blow up hard...if its a really big one it might not be worth fixing due to the high part count as far as replacing parts goes and the hours involved in doing the repair..it can take 4 or 5 hours sometimes to put one back together again.... Lately I've gotten alot of stuff out of other shops that couldnt be fixed and people ship it to me "just to make sure" and I've been fixing them..so its been alot of fun fixing stuff others have turned away but even though..I still dont see many Hi-fonics amps and usually they have minor issues when I do... Good luck with whatever you decide...Amprepairman... [/QUOTE]
