Want the smooth rich tone of the Gold Pin tubes and the earlier breakup of the JJ EL844's? This is our Low Output Gold Pin Option Retube Kit for the Dr. Z Carmen Ghia Heads and Combo Amps. It contains a matched pair of JJ EL844's for power to drop the overall output a couple decibels, a JJ 5Y3S rectifier tube, along with a Gold Pin JJ ECC83S for V1 and a current balanced Gold Pin JJ 5751 for the phase inverter in V2. Just let us know in the comments section if you're looking for an early breakup, a moderate breakup or a later breakup for more headroom in which case we will choose the coolest grades we have available for the power tubes.
