Want a very smooth and rich tone with less grit and the earlier breakup of the JJ EL844's? This is our Low Output Gold Pin Option Retube Kit for the Orange AD30. It contains a matched quad of JJ EL844's for power (which will drop the overall output a couple decibels), a JJ GZ34 rectifier tube along with two Gold Pin ECC83S's one being current balanced for the phase inverter.
