New amp is a kaputt?

I played it for a while, turned it off, and turned it back on with the power and standby switches. Now nothing but speaker buzz at loud volumes levels.

All the tubes I can see are lit up when the power up.

Any idea what could be wrong?

Yea, we are hopefully going to have it swapped out for another one. It sounded absolutely killer before dinner! It's like a Marshall with an extra gobble of useable gain.

Great amp before it went silent!

Check to see if your input and speaker jacks haven't wiggled loose and lost a ground.

All the tube light up though, that's the strange part.

However, that only means the heaters are functioning. A tube can look fine and be malfunctioning or not working. I concur with Scott F to suspect a short or loss of ground because of the loud hum.

I would go with this, especially as a warranty service. Glad to hear it sounded killer before it died. Sometimes QC slips up. Let them replace it.

As I have found personally, a LOT can happen to an amp during shipping. Things can vibrate loose. It only takes one bad solder joint on a ground to screw the entire pooch. I have found myself taking more time on every solder joint over the last few years. Easier to work slowly and methodically and not have to chase gremlins down for a few days.

And yes, a return and repurchase are in order. I wouldn't accept an offer to fix. Screw that. The amp is brand new mass produced. Try another new one. :)

Well it's returned and a new one is on the way to my local GC store.

Expect a NAD here soon :D
