| Shindo preamp rewire 230v to 240v It is safe to plug a 230V Shindo preamp to 240V mains in Australia, no need to rewire the transformer. BTW, all the power transformer in Shindo preamps I know of only comes with two set of 0-100-120V primary windings. It only can configured to ei... | |
| Can I connect a DC power supply to Line 6 Micro Spider with AC "port"? Your amp only has one power supply port, designed to take the OUTPUT* plug of a wall wart AC/DC converter (ie: the PX-2g). jea48 is correct! The PX-2G is a transformer step down 120VAC to 9VAC, it's not a wall wart AC/DC converter. The, "AC... | |

| Denon x4700h DAC change Due to the fire at Asahi Kasei manufacturing (AKM) plant on October 20, 2020, Denon need to look for new chip to continue production of 4700h. Denon AVR-X4700H 2021年春頃よりD/AコンバーターICを変更しています。DACは製品の音質に特に大きな影響を与える部品であるため、その変更に際しましては、回路の再設計およびサウンドチュ... | |
| Accuphase E-280 Voltage Conversion (100V to 120V) Since you have a step-down transformer, you can confirm its transformer taps by power up the E-280 at 100VAC, using a DMM set to AC voltmeter, measure the voltage between yellow - orange, and between yellow - black, you should get both reading of ... | |
| Capacitors for Linn Linto phono stage Recap YES! Go ahead, you did a great job for the capacitors selection! 👍👍 | |
| Capacitors for Linn Linto phono stage Recap @triskadecaphobic You did a great job for the capacitors selection! 👍👍 Some suggestions: IMO, if you want those radial capacitors sat nicely on the PCB, lead spacing is important, and its diameter as well. Newer capacitors for the same rating ... | |
| Voltage conversion of Accuphase E-650 @leecc73 I think the fuse is non reset-able and able to withstand till 300v. here the model i find Littelfuse 36911000000 369 T1A 300V Fuse micro fuse Time-Lag Radial Lead Square Fuse. Thanks for the info, in that case, the fuse will blow if... | |
| Capacitors for Linn Linto phono stage Recap I think it's better to address the power supply issue first. If you suspect the thermistor causing the problem, install a new one and test if the problem goes away, then go recap the power supply. If everything goes well, then go ahead to recap ... | |
| Voltage conversion of Accuphase E-650 Sorry, I don’t know what kind of miniature transformer is it. Measure the size, lead spacing and the output voltage and see if you can find a replacement for 230V. If i turn it on with higher voltage, will it burn? or the fuse will gone. or i j... | |
| Voltage conversion of Accuphase E-650 @leecc73 Thanks for the photos. I think the brown and blue cables are "live and neutral" come from the AC mains IEC socket, the small transformer is connected to it via a resettable fuse (F1), and the K4 is connected to the front panel power sw... | |
| Voltage conversion of Accuphase E-650 @leecc73 It look like a stand-by board, what is the amplifier model number? Can you post a photo of the back of this PCB? Where those brown, blue and red cable came from? | |
| Capacitors for Linn Linto phono stage Recap 1 X Yellow+ Black ?? (see picture. Are these Non-Polarized Capacitors ? do they need replacement too ?) I think the yellow one is a varistor and the black one is a thermistor. If not defective, leave it as it is. 2 X Red ones ?? (see picture.... |
