As far as your unit’s capacitors: if it were me, any electrolytics would be replaced with the exact same values, in either Elna Silmic II’s, their Cerafines or Sanyo OS-CONs. Most DACs have regulators that can be upgraded, as well, to great effect.

(carefully observe polarity, when replacing electrolytics)

How to replace hardwired stock power cord ?
Hello!
I have an old - but exquisite Nakamichi MB10 CD Player. I did come across a post - with very detailed instructions and pictures of modifications possible - someone having modified the unit - basically he changed the stock power to a detachable "IEC" connector - changed some capacitors etc ....
Regretfully I didn't bookmark it - and i cant find it now...have searched the net few time... :( bummer!
Would anyone know - how to go about cutting out the original hardwired cheap power cord and replace it with a good quality one ?
Have I posted this under right topic ?
Any help - much appreciated....thanks

Thanks rodman99999........well I had hoped to replace it with Furutech https://www.futureshop.co.uk/accessories/connectors/iec-power#page=1
I don't mind cutting out the rear side of the case to accommodate this - but then - is soldering just straight forward ? I have no experience in changing the capacitors ....wish I could. However thanks for the info....much appreciated. |
Soldering: Yes. Just follow the existing cord, to it’s connection points. If there’s a star ground, the new cord’s ground conductor to that(perhaps you’ll need an eyelet/ring terminal). If not, try a point on the chassis. If that creates a ground loop, just forget about(cut off) the cord’s ground conductor(you didn’t have one prior, anyway). Same ground rules apply, for an IEC connector, if you choose to pursue that course(per Erik's recommendation). If you can solder/desolder competently at all; capacitors shouldn’t be a problem, providing access to your PC board bottoms is possible/easy. Be adventurous, but- practice first! Tiny alligator clips make great heatsinks and eutectic alloy solders are pleasure/easy to use, if you decide to go there. btw: Elnas for signal path / OS-CONs for power supply |
Get your IEC socket first so you know what size you need, then use this: https://amzn.to/31xVP2v It will take a lot of work and patience. Though honestly, you'll have better results if you forego using detachable cords and replace with a high quality shielded cable like this: https://www.partsconnexion.com/DHLABS-75520.html Check the diameter to make sure it will fit. You may need to ream the original hole. Make sure to get the right grommet so you don't have the cabling touching bare metal. Best, Erik |
