Help! the power light in my amp keeps blowing.

Sign in to disble this ad
I have a Fender Bassman 150 amp and the power light has gone out twice now. The first time it went out I returned it to the store and had their repair man fix it but just over two weeks later it has gone again. I was just wondering what the possible causes of this could be, is it something I am doing wrong? My setup includes an active four string ltd bass and the Fender amp and that's it. Could it possibly be the wiring in the house? I have no idea about electronics and I just want to make sure that there isn't some other cause, I don't want to get it fixed just to have the light blow again.
Any help would be hugely appreciated

I looked at a pic of it out at Sweetwater. The power lamp looks like it's part of the power switch. Could be a whole bunch of illuminated power switches were built wrong, or used defective lamps, or used wrong value dropping resistors (if the lamps are neon), and made it into the pipeline before the problem could be caught. I doubt you're doing anything wrong, 'cause even under the most extreme abuse conditions, the power lamp would be the last thing to go.

Two weeks after it was fixed it failed again? Take it back and keep doing so until it remains fixed!

Put a correct value resistor in series with it. Or find out the voltage and replace it with an LED if it isnt already. I've never ruined an LED, apart from when I hooked it up to a stupid voltage.

Haha, I do overvolt a few of my LED-utilizing creations.... The LED gets a little brighter than before, but they probably wont last as long...
