Want more warmth and definition? This is our Standard Retube Kit for the Orange AD30. It contains a matched quad of JJ EL84's for power, a JJ GZ34 rectifier tube and two ECC83S's one being current balanced for the phase inverter. A nice upgrade from the stock tubes, sweet and warm! Just let us know in the comments section if you're looking for an early breakup, a moderate breakup or a later breakup for more headroom in which case we will choose the coolest grades we have available for the power tubes.
