Want a little cleaner front end and the earlier breakup of the JJ EL844? This is our Low Output SRV Option Retube Kit for the Orange AD30R. This kit uses a JJ 5751 for the input tube which is in-between an ECC81 and an ECC83S in gain. We follow that up with a standard ECC83S for the reverb driver, a balanced ECC83S for the phase inverter, a JJ GZ34 rectifier tube and a matched quad of the low output JJ EL844's for the power section.
