- Changing tubes
o While changing tubes can be intimidating for some, it really is not difficult. First, determine whether your amp is “cathode or fixed bias”. If it is cathode biased (AC15s, being one of our most popular kits, are cathode biased) you can simply swap out the tubes, and you’re good. If your amp is “fixed bias” and you do not know how to make the proper adjustment, please consult a reliable technician. Consult the owner’s manual or decal that is inside your amplifier to confirm which tubes are which.
o Most tubes will come out of their sockets easily with little effort. Simply pull them out (careful not to bang the tube inside the amp when doing so). If you feel resistance, you can use a gentle rocking/circular motion when removing. Before installing your new tubes, ensure that they are aligned properly. The pins on 9-pin tubes (12AX7s, EL84s) can be easily bent and even broken if care is not taken. The new tubes need to go in the same way the old tubes came out. You can see a gap between two of the pins. Make sure to align this accordingly, that the pins are straight and you’re good to go. Octal base tubes (5881, EL34, etc), have a central guide pin with a notch. Align properly and you’re set.
o Clean tube sockets! Whenever you install new tubes, apply a bit of contact cleaner on the metal pins of your tubes then work the tube in and out of the socket a few times. This will help ensure that the tubes pins are making good contact within their sockets.
o Confirm that all tubes are installed in their proper place and well-seated, and you should be ready to rock. If your 12AX7s or EL84s have spring covers or metal shields, re-install these to keep things in place.
o “Snap/Crackle/Pops” – Occasionally when installing brand new tubes, you may hear some noise such as ‘crackling’ ‘popping’ etc. Often this is simply a result of not cleaning the tube sockets. Clean with electrical contact cleaner (see above) and re-install. Play for the amp for 5-10minutes and, likely, the noises will be gone. If you are hearing something more like a loud “hum” or strange “whistling” you may have a bad tube. Identify the culprit and contact us for a replacement.

- How long will my tubes last? Do I have bad tubes?
o Depending on usage, new power tubes can last from a few months up through a couple of years. It is somewhat difficult to gauge, because there are many variables: How hard/loud they are run, how often they are run, in what kind of environment and under what conditions, etc. Power tubes don’t usually STOP working altogether they simply stop working WELL. The best tool you have to discern is…you. If you notice that your tube amp is not sounding or responding as it used to, you may need new power tubes. If you see sparks or smoke or hear some loud pop…shut it down…and take it to a qualified technician. Preamp tubes can usually last for a LONG time (much longer than power tubes), but they do fail on occasion. Again, if you are not very familiar with tube amps and/or your amp in particular…take it to a qualified tech. We are dealing with large (potentially lethal) voltages, so if you don’t know what you are doing…don’t. Even when powered off, these voltages may remain in your amp for some time. Further, tubes get very hot to the touch when in use…so allow time for them to cool off before touching them for removal or replacement.
