| 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.... | |
| Capacitors for Linn Linto phono stage Recap Where in the picture are the additional 24 smd electrolytic capacitors? @triskadecaphobic I found 22pcs of 22uF 50V smd electrolytic caps, except C501 and C601 which too small to read the value in your photo. | |
| Singer HE-2200 Kids Record Player 👍Good luck! | |
| Audio signal sensing auto on/off switch Sure this box can use 12DV trigger, not just a digital input? Yes, I can confirm that this box can be controlled with 12VDC. I have one, what you need to do is connect the green plug to the 12V trigger output. | |
| Audio signal sensing auto on/off switch I've never seen a source with a trigger in that price range. And who would want a one source system? @fuzztone I meant the source to provide audio signal to the subwoofer amp(s), it can be a integrated amp, receiver or pre/pro. Is that... | |
| Audio signal sensing auto on/off switch On one receiver, I have a 12V trigger. Is that 12V linked to ’power on/off’ of the receiver? How many mA can those 12V triggers typically produce (to directly control a relay)? Receiver 12V trigger output usually can provide up to 50-100mA. If ... |
