Burning smell
I have McIntosh 1.25 kw mono blocks. They are around 6 years old. One of them has started emitting an electrical burning smell when playing music. It doesn’t do it when just powered up, only when playing . Does anyone have a possible diagnosis of what component may be failing or what is happening ? Thanks
Check if these caps made in China, then you'll probably find answer. There are also smaller caps that need to be checked around high-heat power supply area where you may see it either out of shape or draining liquid that potentially smokes. Heat damage usually visible Homeowners insurance will compensate you if you continue to listen to music and burn your house :-) |
Czarivey as usual giving bad advice including insurance fraud.
Two most likely culprits are caps and resistors. If it is a cap, it may just be leaking fluid onto a normally hot component. A quick inspection by you (if you know how to open it up) or a tech should identify the hot component. If not, then power it up with the top off and a thermal camera will identify the hot component immediately. Should not be expensive fix.
and if you can afford this amp, you don't need to commit insurance fraud.

@carlsbad2 don’t be so pessimistic. The amps do burn especially when not attended and listening music on the background and you are bringing fraud ideas all of a sudden? Note it’s not me bringing those. YOU DO SIR. Those big macs should have all sorts of risk teams if anything goes down South like that. If ever anything like that reported that big macs caught fire, there will be LOTS of LOUD NOISE from consumers reaching out the press and media. If anything found funky like that that could cause fire, you may be entitled for the safety recall repair. Assess the situation and report it to manufacturer.
