This kit is for those of you who want more drive and sustain from the front end. A matched pair of JJ EL84's, a handpicked high gain ECC83S for V1, and a high gain balanced ECC83S for the phase inverter in V2. These will not hurt your clean tone but as you dial in gain you will just get a bit more. 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.
These amps are fixed biased, there is no bias adjustment to be made. The amount of clean headroom you’ll get from the power section is somewhat dictated by the grade of power tube used. A cooler grade of EL84’s will give you more clean headroom, whereas a warmer grade will give you earlier breakup. If you order online, leave us a note in the comments section letting us know your headroom preference (max headroom, middle of the road or early breakup).
