| Voltage conversion of Accuphase E-5000 @foolishman Glad to hear you have successfully converted your C-57 to 120V. I hope some forum members will find this information helpful. | |
| Voltage conversion of Accuphase E-650 In addition to the above changes, if there is an auxiliary transformer, it will also need to be changed from a 100vV model to a 220/240V model. | |
| Voltage conversion of Accuphase E-650 @susurin Yes, K3 to K7 and K4 to K8 will convert 100V to 220/240V. Remove J1 and J3 and install a jumper to J2, which will convert the soft-start resistor array from 100/120V to 220/240V. | |
| Voltage conversion of Accuphase E-5000 @foolishman It looks like Accuphase's typical preamp dual transformer setup, with jumpers J1, J2, J3 and J4, J5, J6 for voltage selection. Moving the jumpers to J2 and J5 will convert to 120V. Before converting the voltage to 120V, testing th... | |

| Cambridge Azur 851A Problem! Help!! What model is the replacement switch? Can you provide a link? "Standby mode" 2.1 watts indicates that there is a problem with the standby power supply, and it is best to send it to a service center for repair. | |
| Driving speakers in more than one room I’ve seen on this topic seem to indicate that connecting a fixed line out to an input on another unit will sometimes work and other times not, depending on how the input and output circuits are designed on the two integrated amps/receivers involv... | |
| Ripple current Q for amp capacitors I’ve been incredibly paranoid of not getting the right part in there. Question on that above though as that’s interesting.. I assume at the time EAD had capacitance testers, and that every cap in this size they got, would be tested first to see ... | |
| Ripple current Q for amp capacitors Can the CD store basically 175,000uf if needed? No, that’s not how it works, modern electrolytic capacitors typically have a tolerance range of ±20% being a common standard. This means that a capacitor labeled with a specific capacitance value ... | |
| Ripple current Q for amp capacitors As far as which of the two caps to use: you’d have to do a little bit of research and see if both versions of the CDE caps were available at the time of the EAD1000 production. If so, then the designers made the choice. According to the specif... | |
| Accuphase E-280 Voltage Conversion (100V to 120V) @sonicrage The Accuphase E-280 power transformer has two primary windings, connecting the windings in parallel will produce a 100V or 120V primary, and connecting the two windings in series will produce a 220V or 240V primary. Above is the 10... | |
| Help to Identify AC Connector DC blockers are easy to make if you're handy. Otherwise, try the Emotiva CMX2. | |
| Help to Identify AC Connector It is a direct wiring socket, please refer to the manual for wiring method: https://www.epever.com/wp-content/uploads/2021/09/IPower-Plus-Manual-EN-V3.4.pdf If you prefer to use some kind of connector, maybe you could try some wire ferrules, jus... | |
| b & w 804 s speakers are cutting at not so high volume What's happening on both speakers is rare, maybe an upstream component that's the culprit? | |
