It's no secret that Stevie played his amps cranked and preferred a little cleaner sound from the front end allowing you to hear more power tube breakup. This kit uses a JJ 5751 to replace the 12AX7 which is in-between an ECC81 and an ECC83S in gain, a single JJ 6V6S for power, a JJ 5Y3S.
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 grade we have available for the power tube.
