Only a couple months after getting my Super-Champ XD, It appears I have blown a Power Tube.

When I turn on my amp, I am getting popping and buzzing coming out the amp speaker, and you can see the power tube creating pops of light when ever the I hear to pops.

Fender's Specs say the Power tubes are 6V6, and the one Preamp tube is a 12AX7, so would anyone recommend a good replacement tube? I am probably going to retube all the tubes, just to get a clean start.


Thanks,

Joe

Hi PinkFloydJoe,

You might want to have a look at the rest of the amp components, especially the power supply caps, before installing new tubes as it is possible that something is causing the tube to fail, or it might be just a bad tube.

Lots of great choices, but for a great bang for the buck 6V6 I like the Electro Harmonix (EH). This is a fantastic sounding tube, rich sound with great harmonics and very rugged.

For the 12AX7, it isn't much of a factor for the amp sound, and no need to pay extra for a balanced tube as only half of it is used for preamp and half for pi. This one will probably work fine.

Any tube, including "NOS" or any top brand, can have problems when first installed in an amp, make sure you buy from a place that guarantees the tubes allowing return and replacements. :idea:
