Fluctuations of the loudness of speakers???

I've just discovered something that has me concerned. Sometimes while listening to music, either of my two speakers (that are probably not broken in yet)suddenly loses volume (not all the way but still very noticable)...it's like they lose juice suddenly. It's more noticable at lower volumes but happens at higher regardless. I don't know if to blame speakers, or cables, or if my power outlet has a problem with my 250 wpc amplifier. Sometimes a simultaneous "crackling" sound occurs. I have no idea if the problems are related but at keeps me up at night :-( Any ideas greatly appreciated...

Recheck your cables...(interconnects and speaker) - make sure they are clean and tight.

To change a tube, open the case, just pull out the tube when cold,,,pull straight up - don't twist it... and replace with the same tube type and number. You might have some dirt on the pins of the old tube, so I would remove and replace the same tube to see if the problem goes away.
