[QUOTE="John Roberts, post: 42838, member: 126"] Re: Is it safe to use this amp? I have never been a fan of those amps... IMO (and what would I know?) it was a very old (and tired) design repackaged using modern SOTA (brand new at the time) SMD technology, by a non power amp guy. OK I feel a little better now... In case you aren't joking, at a minimum you need to replace the fried SMT resistors that look like miniature charcoal briquets in your picture. if you are not handy with making your own repairs ask crown for a quote... but don't just bend over and ask for a kiss, because they may want to sell you a new PCB. I'd buy a new different amp before that. It doesn't look as bad as some I've seen around... if those are the worst of it it looks fixable, and maybe cheap, if it's just replacing those burned up emitter ballast resistors... it looks like they used two in parallel to try to get a little more power handling out of them... Hmm how well did that work out? :-) JR [/QUOTE]
