have 2 in for repair with customer complaint of low gain. both amps apparently left on 24/7 for 13 years! looks like a busy day looking for faulty electrolytics....
Привет у меня есть вопрос. Азъ хочу построить квадро систему. Можно-ли будет подключить 8 штук колонок, 6 ом 350 ватт Биварингом по 4 штуки? Hi I have a question. Az I want to build a quad system. Will it be possible to connect 8 pieces of speakers(monitors) 6 ohms 320 watts bivariated by 4 pieces per channel?
Hi, I have a question: I recently bought a second-hand PC9501N amplifier. Both channels sound ok, but there is a difference of 3db between channels A and B, (according to the dB meter) and a difference of 0,5V between outputs (applying the same signal, despite of being in stereo, mono or bridge). No clipping or distortion. No shorts or open transistors. The power supply delivers the same voltage to the 2 channels. Why does this occur? Maybe I should adjust the bias? Thanks in advance
Sir I have question... My amp Yamaha have trouble like yours....but after i repair, one month leter the amplifier broken again in the same case ( resistor 5w6,8ohm) ...the resistor open again....two time i change the resistor Can you help why resistor open...??? Thanks
Pour protéger contre les poussières et oxydation des composants il existe un filtre que l'ont ajoutes sur ouilles de la ventilation comme les filtres à hotte de cuisine il est prérable de choisir la couleur blanc si votre filtre devient grise il est temps de la remplacer tous ceci évite le désagrément
