I was playing the Durango Meltdown Festival, went to turn on my Bassman 100T, heard a fizzzzzz... No pilot light, tubes glowing, no sound. Less than a month old. Took it to the dealer who sent it in for repair. Micro fuses blown, Fender has no stock to replace them per the repairman. WTF? Three weeks now. Anyone else have this problem? I'd like to hear from someone at Fender. :x :?

A fuse is there to protect the amp's component .

It blow for something , why ? What the repairman find wrong in your amp ?

Or he just want to put another fuse........wich will blow on the bench and you wait another 3 weeks or if you are bad lucky it will blow when you play next gig .

I must fix the amp first .

Yes sometime a fuse blow for nothing with no problem with amp. Bad wall outlet plug at this festival or bad 120 volts power ?

Fuse in stock ; the amp is on warranty
Repairman must use Fender parts IMO

Easily available in any good electronic distributor IMO

One of the solid bench troubleshooting procedures is to look at a schematinc and see what voltage line the bad fuse fed. Then, making certain that the system is not plugged in, use a multi meter in a mid resistance scale to isolate which component failed and is causing that voltage distruibution line to draw excessive current. Once the component is located and replaced, the same testing is done over again to see if there were any other circuit components affected by the original failure. If everything else checks OK, a 'properly trained' technician will use a fast acting circuit breaker rated the SAME as the blown fuse clipped into the fuse holder or pigtails and run the amp. A technician who sees a bad fuse and WAITS to do troubleshooting while a replacement fuse is ordered, does not necessarilly have a proper mindset or training for troubleshooting.

You may wish to reconsider your dealer's choice of a service facility and see if there is an option for you....


Good Luck...
