Ampeg SVT-CL sound Problem ???

Bad day with my Ampeg SVT-CL 2001. During rehearsal, after some playing for around 10 minutes or so, the amp begins to crackle (all speakers). Tried some other cables but no improvement. The actual sound here:



After setting the amp in stand-by mode and turning it on again, it begins to crackle for a while without playing something. Than it stops, but still crackles while playing.
After setting the amp off completely, and turning on, first the sound is good. Then after a while crackles begin again :(. Not happy.

The tubes are fairly new, around a month old. And the head always stays on its place. Does anyone know what could be wrong with it? I have no clue. Could it be a tube problem?

Yes it could very well be a tube problem, probably a pre amp tube.
New production tubes suck.:-(:bassist:

I would stay on top of it. Most times Tube vendors give you a 90 day warranty. Tubes are made so shotty that sometimes they show up damaged. I've had techs test tubes and they show fine only to find out that as soon as they are burned in they are not. Almost all problems I have had with these amps in the 6 years I've been playing them trace back to the power tubes.
