Power Tubes

Power tubes, or output tubes, continue to amplify the signal sent from the preamp section so they can drive the speakers. Each set of power tubes will draw a different current (measured in milliamps), affecting how fast the signal gets passed through your amp. The speed of this current will have a big impact of the tone of your guitar amp.
