Want all the gain you can get? This is our High Gain Option Retube Kit for the Orange AD30. It contains a matched quad of JJ EL84's for power, a JJ GZ34 rectifier tube and two handpicked High Gain ECC83S's one being current balanced for the phase inverter. 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.
