Need less headroom and more overall crunch? This is our Low Output High Gain Retube Kit for the Orange AD15. It contains a matched pair of JJ EL844's for power (which will drop the overall output a couple decibels), a JJ GZ34 rectifier tube and two handpicked High Gain ECC83S's with one being current balanced for the phase inverter. 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.
