Is the sweet spot for your Ghia just a little to loud for you? This is our Low Output Standard 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 JJ ECC83S for V1 and a current balanced 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.
