VHT GP3 : Positions des lampes (12ax7)

Bonjour,

Extrait de mon avis AF, je le met dans la rubrique FAQ pour plus de facilité de recherche

Chaque lampe a 2 fonctions, de gauche à droite en regardant le GP3 de face on a :
V1 = 12ax7wb Sovetek : unity gain buffer stage (effect loop driver)
V2 = 12ax7wb Sovetek : Input gain stage 1 & signal splitter/driver for all 3 channels - Both triodes opperating in parallel
V3 = 12AX7 China : Gain Stage 2 for Rythm & Lead Channels
V4 = 12AX7 China : Gain Stage 3 & Tone control driver for Rythm & Lead Channels
V5 = 12AX7 China : Gain Stage 2 for Clean Channel - Gain Stacking Stage (stage 4) for Lead & Rythm Channels - Gain stacking Stage active when gain toggle is set to HI Gain
V6 = 12AX7 China : Low output dual single-ended power amplifier stage - Both triodes opperating in parallel
