Need less headroom and more overall crunch? This is our Low Output High Gain Option Retube Kit for the Orange AD30R. It contains a matched quad of JJ EL844's for power (which will drop the overall output a couple decibels), a GZ34 rectifier tube, a standard ECC83S for the reverb driver along with two handpicked High Gain ECC83S's with one of them being current balanced for the phase inverter.
