on my vc30:
matched quad JJ EL84's on power section
preamp:
V1 (input): Electro Harmonix 12AX7EH
V2 (ch2): Some 12AX7 with no brand that i found lying around
V3 (phase inverter): Electro Harmonix 12AX7EH
meron pa ako isang extra 12ax7eh, yun dapat kay V2, pero i duno, weird, mas maganda tunong sa V2 nung walang brand. might try to put a 12at7 sa v2, parang mas maganda low gain kay v2 kasi
