CE1000 Mechanical Hum Problem

Recommended Posts

I have a CE-1000 that is just about brand new.I put it in my equipment rack intending to use it as a rear surround channel (it is in a very large home cinema system) and it has a very loud mechanical transformer hum. :huh: There is no hum from the speakers, this is strictly a mechanical transformer hum. Any easy way to fix this? It is annoyingly loud. The amp is on a 20 amp line that is steady at between 118 and 120 volts.

Saw that. Issue is that it hums whether it is in the rack, out of the rack sitting on soft carpet, or if I hold it in my hands. Definitely a pretty hefty transformer hum. It is exacerbated by being mounted in the rack (tightly), but still there none the less. I have other amps in the rack and they don't hum anywhere near this extent.

I have never done this fix but it was on a web site that I read some time ago. The claim was that by placing a toothpick or two in the windings of the transformer it stopped the vibration or hum coming from the unit. Caution:dealing with potential danger here but others responding claimed it worked. I make no such claims or guarantees. :blink:
