I have a Peavey Renown Solo Series guitar amp. It's 450 Watts. It's a great sounding amp. My problem is that now when I turn it on, the light comes on but there is no sound. This used to happen a few times in the past but what used to work was whenever I would turn up the volume up pretty loud, THEN the amp would come blasting on. So I would turn the volume down to wherever I wanted it and it would be fine. This was very rare whenever this happened since 95% of the time whenever I turned on the amp, it came on fine. Now no matter how loud I turn up the volume, it doesn't come on. I need help right away! Can anyone there help me?!

If the amp is not turning on at all (red light near the power switch is dark), the fix may be as simple as a blown fuse. With the amp unplugged, remove the head from the case. you'll see three fuses, two on the circuit board, and another connected to the wire coming through the bottom of the case from the power supply underneath. If the power supply fuse is blown, replace it with a 250v 5a fuse (there should be a label in the case with the fuse specs - double check it). I own two '83 Renown 212s and both had this issue. Yes, 160w output...and loud as hell.

You'll need to have the amp in for some troubleshooting. It's not easy to say what the problem is and it could be a number of things. Also, that 450 watts is the power the amp uses, not how much audio power it puts out. The Renown was originally made in a 160 watt format and on the back of it, it says "450 watts" on the left side of the back, but that is the power it uses... This is why I say you should take the amp to a shop...
