Want a really smooth and rich tone with less grit? This is our Gold Pin Option Retube Kit for the Magnatone Super 30 Combo Amps. It contains one Gold Pin ECC82 to replace the 12AU7 along with six Gold Pin ECC83S's with two of them being current balanced for the phase inverters in V6 and V7. The default power tubes are a matched quad of the JJ EL84's but you can configure this kit to use the JJ EL844's by clicking on the "Customize" button!
