Preamp Tonekit 12AX7 (5)

Keep it simple with the basic 5 x 12AX7 JJ preamp tube kit or try some tube rolling. This is a the "5 12AX7" version of the Doug's Tubes preamp tube cocktail kit and we've received great feedback on it. The tonekit allows hi-fi and guitarists alike to experiment and "tube-roll" preamp tubes in different slots of their amp. Currently we're recommending the following :

V1 - Gold Lion Standard pin ECC83(V2 in the Express series amps)

V2 - Ruby 12AX7ACZ HG(V1 in the Express series amps)

V3 - Ruby 12AX7AC5 HG

V4 - JJ ECC83(V5 in the Express series amps)

V5 - Psvane ECC83(V4 in the Express series amps)(JJ ECC83 with high gain kit)
