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. Well, this works really well with the Balinese amps too! The kit uses a JJ 5751 for V1 to drop the gain along with two ECC83S's with one being current balanced for the phase inverter in V3 and a GZ34 rectifier tube. The default power tubes are a matched pair of the JJ 6L6GC's. With the Customize option you can configure this kit to use the JJ 5881's or the JJ 6V6S's which will drop the power output a couple decibels and also choose between the JJ GZ34 or the JJ 5Y3S rectifier tube.
