speaker problem

quick question
after months of problem free listening, when i turned on my amps and cdp tonight i heard a low crackling noise coming from my left channel, specifically the tweeter.
powered off and checked all connections, ics and speaker cables, and everything seems in order, nothing loose.
when the power amp is off, no noise whatsoever.
is this a sign there is something gone wrong with the left tweeter?

associated equipment:
rogue mag 99 pre
rogue 88 power amp
metronome cd1 mk1
msb link iii
alpha core ics
alpha core mi2 sp cable
ps audio 600

any thoughts? i listen everyday for hours and have been for months w/o this problem.
thanks in advance

Consider checking the tubes on your preamp by switching them over from right to left and vice versa and check if the noise transfers to the other speaker.

goodluck

HI fujindemon
the tubes may have low hours on them ... but they were probably takenout -- shipped to you and put in --- tthey probably bounced around alot ....

and that is a good idea fromRmml --- try switching the tubes on the amp from left to right and also the preamp if the amp had no effect ... remember-- if you do not switch them back you need to rebias ....

probably a good idea after all is done just to rebias everything

agree it sounds like a tube failing...
What happens when source equipment is shut off & just the power amp is left on? That will help to locate the culprit / eliminate some of your variables in the puzzle.
