The Mullard KT88 is a top-quality tetrode tube. It's an exact copy of the tube made by Marconi-Osram for Marshall in the late '60s and '70s. This tube will give you a powerful, balanced and detailed sound with full bass. The KT88 power tube can be used as a replacement for any 6550 tube, or can be integrated into the iconic Marshall Major to reproduce its original sound.
