Some amps do this automatically, but many do not - particularly in the world of guitar amps. Just like the idle of your car may need adjusting when a major change is done to the engine, new power tubes need their idle (the "bias") adjusted to make sure the amp sounds as good as possible. What does it mean to "bias" the amplifier? Thru the tube store you can continue to by tubes from the same "groups" which means if you buy a set from a group at the tube store, and have the amp biased, you just continue to by from that group and don't need to rebiased the amp.ĩ. I know you still don't believe me, but even places like tells you to rebias Power Tube's each time you replace them. Biasing should only be necessary if your amp goes out of bias (a sign of a serious problem) or if you change tube-type (like EL-84's to 6V6's). It's not a bad idea to have your amp biased every few years (maybe every second or third power tube swap), but I don't believe it's necessary every time. If you want to get anal about it, you can have it biased, but the plate voltages should be fine for a new set of tubes. Make sure you replace the power tubes (four EL-84's) with a matched quartet, all four at once. The only real problem with it is that there isn't a lot of room to maneuver or see what you're doing, so lining the tube pins up can be kind of a bitch.Īs far as biasing, you should be fine just swapping them tube-for-tube. There are just a couple panels that cover the tubes (that also serve to keep the tubes well-seated) that you'll have to locate and remove.
