Flickering power light??

Sign in to disble this ad
Hello! I did a search (here and abroad) but couldn't seem to find what I was looking for.

I just upgraded to my first "real" amp - an Acoustic b200h. It arrived yesterday, and since the cab (115) will be arriving today () I hooked it up to my 8ohm Workingman's 210 to try it out.

The amp sounds great and is loud as all get out, but I noticed that the power light was intermittently flickering in reaction to the signal, although not at the signal's peaks as I would expect. At most, the gain and volume were set around 9 o'clock so I can't imagine that I was pushing it too hard. The manual says nothing about a built-in limiter and the amp has a separate LED to indicate clipping. The max load is 4ohms so I don't think the cab was the problem either.

Is this normal or usual? Any ideas as to what might be happening?

All expertise and suggestions are greatly appreciated! I would hate to blow up my amp on day 2.

Cheers.

If the power light is inside the power switch itself it's probably a neon. These can react to vibration but not often. Some just flicker anyway. If you have concerns take it back and get another one.

It's a jewel light, not part of the switch...

Might still be a neon lamp in there.
