Voltage conversion of Accuphase E-650 Victor, I'm glad you figured it out. 👌✌👍 | |
Voltage conversion of Accuphase E-650 Two possibilities: 1. The incandescent light bulb too low in wattage 2. Short circuit @zeptul According to the specs E-650 draws 168 watts @ idle. Please try a 250 or 300 watts bulb. If that does not light up the amplifier, you need to check ... | |
Voltage conversion of Accuphase E-650 When the amplifier is turned on through an incandescent lamp, the amplifier indicators do not light up. It should be? What’s the wattage of the incandescent lamp? | |
Hum on Tube Amp - Can't find source would speaker feedback do that? IRS Beta @ervikingo Have you tried connect a different pair of speakers on your Manley Snappers? | |
Krell Fpb 300 engage capacitor for tube preamp @null1 IIRC, the jumpers are between the two yellow capacitors, can you post a close up image? | |
Accuphase A-65 Voltage Conversion (100V to 120V) Yes! 👍 | |
Accuphase E-408 voltage conversion Glad everything went well! Cheers 🥂 | |
Accuphase E-408 voltage conversion @zeptul Looks perfect! The bulb lit up in the first second is due to inrush current as long as it dim down after that. It is perfectly OK! Please go ahead plug it in directly to the mains outlet. | |
Accuphase E-408 voltage conversion @zeptul For the soft start resistors, J3 provides highest resistance and should be good for 220V/240V mains, therefore no changes required. | |
Heat sinking op-amps - any audio improvements? I know it sounds crazy, but maybe keeping them even a little bit cooler might be beneficial. Crazy? Not really. Thermal Design Basics - Analog Devices | |
Heat sinking op-amps - any audio improvements? I’m debating trying some on some NE5532’s. Worth the effort? Why not? It's an inexpensive tweak and can easily reverted. | |
Accuphase E-480 just wanna confirm that change its 100v for 120v, I only need change below jumper setting J4 -> J5 J10 -> J8 J6 -> J11 From previous experience of Accuphase amplifier voltage conversion, change 100V to 120V only required move two j... | |
Accuphase E-480 meter flicking @zensview I suspected your E480 voltage conversion was incorrect, can you provide images of the power board (front and back), maybe we can figure it out. | |
Accuphase E-408 voltage conversion @zeptul please counter check if the jumper positions are correct. If the jumpers position are correct, the setting should be as below: 100V mains = J5, J7, J9 120V mains = J4, J6, J9 220V mains = J5, J8 240V mains = J4, J8 ... | |
Accuphase E-408 voltage conversion Thanks @zeptul for the images, I will check it out and get back to you later. |
