J’aime bien ouvrir mes appareils Hifi pour voir ce qu’on y trouve \u00e0 l’int\u00e9rieur ! Ce matin, pour m’occuper en attendant la fin d’une belle averse, j’ai ouvert l’ampli dont je vous parlais l’autre jour<\/strong><\/span><\/a> –et dont le prix a inexplicablement et assez consid\u00e9rablement augment\u00e9 depuis son achat…<\/em>-, parce que si je savais qu’il contenait un ventilateur, je ne l’avais encore jamais entendu fonctionner. jusqu’\u00e0 hier, donc, o\u00f9 il s’est mis en marche, musique \u00e9cout\u00e9e un peu fort et temp\u00e9rature ext\u00e9rieure \u00e9lev\u00e9e aidant.<\/p>\n

Le bestiau est assez rempli ! Outre le confortable transformateur toro\u00efdal et des condensateurs de filtrage de bonne taille –mes rapides recherches laissent appara\u00eetre que la marque anglaise fut la toute premi\u00e8re \u00e0 utiliser ce type de transformateur dans un ampli, et ce d\u00e8s 1968 : depuis, la pratique s’est r\u00e9pandue dans les amplis de gamme moyenne ou \u00e9lev\u00e9e, surtout en Angleterre ou aux Etas-Unis<\/em>-, on trouve un radiateur cons\u00e9quent sur lequel est branch\u00e9 ce fameux ventilateur. On aper\u00e7oit aussi les quatre transistors de puissance –une paire par canal<\/em>– et les modules num\u00e9riques. Le tout semble assez propre, mais je me suis content\u00e9 d’observer sans rien bouger… –Cliquer sur l’image pour la voir en plus grand<\/em>-.<\/p>\n

\"\"<\/a><\/p>\n

Aux mesures, l’appareil se r\u00e9v\u00e8le tr\u00e8s convenable, et les sp\u00e9cifi\u00e9s du constructeur sont respect\u00e9es ou d\u00e9pass\u00e9es : la puissance sous 8 ohms est de 2×110 watts et celle sous 4 ohms de 2×190 watts –le fait de quasiment doubler cette puissance en divisant l’imp\u00e9dance de moiti\u00e9 est un excellent signe, plus rare qu’il n’y para\u00eet alors que cela devrait th\u00e9oriquement toujours \u00eatre la norme<\/em>-.<\/p>\n

\nDu coup, l’averse est pass\u00e9e, le soleil s’installe gentiment et je vais remplir le frigo !<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
