Want a really 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 Dual Terror. It contains a matched quad of JJ EL844's for power and four Gold Pin ECC83S's with two being current balanced for the phase inverters in V2 and V4. A nice upgrade from the stock tubes, lush, smooth and an earlier power tube breakup!
