Want that FAT mid and high end sparkle of the ECC803S and the earlier breakup of the JJ EL844's? This is our Low Output ECC803S V1 Option Retube Kit for the Orange Dark Terror, Jim Root Terror and the OR15H Amps. It contains a JJ Long Plate ECC803S for V1 for a little lower gain with big thick mids and a little more sparkle in the highs. We follow that up with a matched pair of JJ EL844's for power (which will drop the overall output a couple decibels), a JJ ECC81 for the FX loop, and two standard ECC83S's with one being current balanced for the phase inverter in V4.
