Want the earlier breakup of the JJ EL844's? Are you looking for a great clean channel and more gain in the lead channel?? This is our Low Output Normal Clean - High Gain Lead Option Retube Kit for the Orange AD30TC and AD30HTC Amps. It contains a matched quad of JJ EL844's for power which will drop the overall output a couple decibels. We follow that up with a GZ34 rectifier tube, a standard ECC83S for V1, a balanced ECC83S for V3 and two handpicked High Gain ECC83S's one of them being current balanced for the phase inverter in V4.
