This feature allows any player to easily adjust pairs of the YBA300's power tubes without fear. LED indicators on the rear of the amp show proper tube function and status. In the rare event of a tube failure, the YBA300 locks out the problem tube and its partner, allowing the amp to finish the show on the remaining active tubes. The LED display clearly shows which tube needs service.The YBA300 is not just powerful and reliable, but also versatile. It ships with twelve hand-selected and tested 6L6 power tubes, delivering a truly classic hi-fi smooth tube tone. For players looking for a more aggressive bass sound, the stock 6L6 tubes can be easily changed to any high-quality EL34 tube set and be rebiased in the field. This makes the YBA300 essentially two amps in one versatile chassis.Simple controls make it easy to dial in virtually any bass tone. The Traynor YBA300 is made in Canada using solid plywood cabinet construction, heavy gauge steel chassis, high-quality pots and jacks.
