Want a very smooth and rich tone with less grit? Looking for decreased headroom and an earlier breakup at the same time? This is our Low Output Gold Pin 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), a GZ34 rectifier tube and four Gold Pin ECC83S's with two of them being current balanced for the phase inverters.
