Location: Colorado Rocky Mountains | First, there’s no sound. Second, it shorts out, the power-on jewel light extinguishes itself, and everything goes dead, in relatively quick succession. Then its all quiet as everybody stares. Next comes the smoke, just the hint of a slowly curling swirl at first, but quickly increasing to a noticeable charcoal-colored cloud exiting from the amp's open back. Then the disheartening odor of burning metallic, melted solder and fried wire insulation. Eventually comes a trip to the amp doctor and, finally, a wallet thinning repair bill. First amp I’ve ever blown up in over 50 years of playing. I wish it was because of the huge power chords I was pushing through it, or that I kicked it over in the middle of a great southern blues riff, or after using it as a launch platform for my mid-air windmills. Nope. This is what happens when you mix the pre-amp tubes with the output tubes. Somebody should tell Fender to post a warning on their tube charts that you have to read the damn things backwards. What an idiot. I should stick to cannon-sitting. |

Your humble confession may save us a lot of grief. What Amp is/was it? |

What happens when a tube amp blows?
