Acoustat TNT 200


I have an Acoustat TNT 200 that makes a click noise inside the amp while operating. I noticed this when I had the stereo at a very low volume. The sound from the speakers is perfectly fine no unusual noise ect. is this normal for this type of amp, or could there be a problem?

Thanks

It's normal. The stainless steel chassis is the reason. If you leave the amp on all of the time, it will stop after a day or two. Nothing to worry about. Don
Thanks for the response. One last question if I may..I also noticed (hard not to) that it makes a whir like sound and slight hum when powering up then becomes clear. Takes about 2 seconds. Is this too normal?
Seeking scanned copy or photocopy of Owners Manual and, possibly, schematic of the Acoustat TNT 200 power amp. Will compensate for effort. Thanks.
