Apr\u00e8s avoir beaucoup travaill\u00e9 sur des Vox AC30, des copper panel<\/strong> du d\u00e9but 60s aux Top Boost<\/strong> des ann\u00e9es 70 - qui ont vu le pire et le meilleur chez Vox - j'ai voulu cr\u00e9er ma version de l'AC15, autour du mod\u00e8le de 1961-65 et en y mettant le fruit de mes exp\u00e9riences.<\/span><\/p>\n

Am\u00e9liorations et modernisations :<\/strong><\/span><\/p>\n

 <\/p>\n

Sur le Vox AC15 vintage, la vitesse du Vibrato\/Tremolo<\/strong> se r\u00e8gle par commutateur rotatif \u00e0 3 positions (comme l'AC30).<\/span><\/p>\n

\u2022 J'ai remplac\u00e9 ce commutateur par un potentiom\u00e8tre pour plus de pr\u00e9cision dans l'utilisation.<\/span><\/p>\n

\u2022 Vibrato et Tremolo sont commutables par push-pull<\/strong> du potentiom\u00e8tre Depth<\/strong>.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

L'AC15 original n'a pas de corrections graves\/aigus, le circuit Top Boost<\/strong> \u00e9tait r\u00e9serv\u00e9 \u00e0 l'AC30.<\/span><\/p>\n

Les Vox sonnent magnifiquement bien sans le Top Boost, mais comme petite extravagance luxueuse, j'ai ici ajout\u00e9 le Top Boost.<\/span><\/p>\n

 <\/p>\n

\u2022 Et pour pouvoir utiliser le circuit original, il est bypassable<\/strong> sur le potentiom\u00e8tre Bass<\/strong>.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

\u2022 Le commutateur Brillance<\/strong> du circuit original est report\u00e9 par push-pull sur le potentiom\u00e8tre Treble<\/strong>.<\/span><\/p>\n

\u2022 Adjonction d'un Standby<\/strong>.<\/span><\/p>\n

\u2022 C\u00e2blage optimis\u00e9 sur turret boards bak\u00e9lite RS<\/strong> originaux.<\/span><\/p>\n

\u2022 L'utilisation de potentiom\u00e8tres push-pull permet de garder l'apparence originale, avec simplement un potentiom\u00e8tre suppl\u00e9mentaire en fa\u00e7ade.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

 <\/p>\n

Le canal I<\/strong> avec sa lampe ECC83<\/strong> est typique des Vox, avec un son tr\u00e8s direct, qui crunche lorsqu'on passe les 2\/3 du volume.<\/span><\/p>\n

 <\/p>\n

Le canal II<\/strong> utilise donc une pentode EF86<\/strong> et cr\u00e9e rapidement une saturation tr\u00e8s chaude, riche et pleine d'harmoniques.<\/span><\/p>\n

 <\/p>\n

L'ampli drive sans probl\u00e8me un baffle 4x12<\/strong>, et on obtient alors un tr\u00e8s gros son, tr\u00e8s rock avec une compression naturelle.<\/span><\/p>\n
