What Is Bias in Amps?īias is a measure of the amount of current that is flowing through the vacuum tubes within your amp.
It’s worth any price that they charge you, because it means that you won’t be risking your life. You should always get a professional to do it. Short sleeves should also be worn, as well as safety goggles.īut above all, we do not recommend that you try working on your amp at all. On top of that, remove any jewelery you’re wearing, because charge will go through that. The tubes inside it get extremely hot and dangerous, so DO NOT touch them.Īdditionally, if you’re touching something in the amp then you must keep one hand at your side, which will prevent current being able to run fully around your body – in a worst case scenario. You must make sure you unplug it regardless. Their chassis contains 500V DC, which is a voltage that will kill anyone exposed to it.Įven when the amp is unplugged, it is still dangerous and continues to hold charge. Tube amps are full of charge and can kill you instantly. We really, really recommend that you get a professional to do it. You should under no circumstances try biasing a tube amp, or even fiddling with the insides of one, if you don’t know what you’re doing.
