Traynor's all-tube 300W YBA300 bass amplifier head was built from the ground up with hard-touring musicians in mind. Able to deliver full power at 2 or 4 Ohms, and stocked with (3) 12AX7s, (1) 12AU7, and (12) 6L6 tubes, this head can give you that ever-popular tube sound without sacrificing reliability.

Highly effective and straightforward tube bias adjust with clear and concise LED display ensure any player can 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 rare cases where a tube fails, the YBA300 will lock out the problem tube and its partner, allowing the amp to finish the show on the remaining active tubes. LED display clearly shows which tube needs service.

The YBA300 ships with twelve hand-selected and tested 6L6 power tubes, delivering a truly classic hi-fi smooth tube tone. For players looking for more aggressive bass sound, the 6L6 tubes can be easily changed to any high-quality EL34 tube set and be rebiased in the field, making this YBA300 essentially two amps in one versatile chassis.

Simple Controls
This amp head is made in Canada using solid plywood cabinet construction, heavy gauge steel chassis, high-quality pots and jacks and is covered by a 2-year unlimited warranty in the USA and Canada.
