Looking for a vintage vibe? This is the ECC803S V1 Option Retube Kit for the Classic 30, Classic 50 or Delta Blues. This Retube Kit contains an ECC803S for V1 for a little less gain, a thicker mid and a little more high end. We follow that up with a standard ECC83S for V2, a graded high current ECC83S for V3 and a matched quad of JJ EL84's for power.
Just let us know in the comments section if you're looking for max headroom, moderate or an early breakup so we can select a proper grade for the power tubes.
