Yellow Jackets converters are a type of specialized adapter which permit the use of EL84/6BQ5 power tubes in place of 6V6, 6L6, E元4, and 7591 type vacuum tubes, allowing to harness the musicality of EL84 vacuum tubes in amps that don't use them already.
Additional space for larger capacitors to give users upgrade options. Different tubes for rolling: 6AQ5 and 6V6 series.
