Anyone having a problem with the clean channel on the series one 200w head? I've had the had for little over a month and im noticing that the clean channel cuts out and will have no sound when used for awhile playing but the other channels work just fine but when i let the amp cool down the clean channel works fine again. It also seems like the volume will decrease as playing when played for awhile. Is this due to heat should i install fans in the back panel or does it need a repair. I've got a show coming up and im hoping that its a quick fix because of the 3 month wait it took to get this head when ordered.

I'm a bit late replying but, as a reference for everyone else:
That's a valve problem of the Clean Channel.
Just replace the valve and that problem will go away.

Sounds like the Pre Amp tube for the clean channel
