Want a very rich and smooth tone with less grit? This is our Gold Pin Option Retube Kit for the Orange AD30R. It contains a matched quad of JJ EL84's for power, a JJ GZ34 rectifier tube and three Gold Pin ECC83S's with 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.
