Recap for Mainboard [1541 version]

Post by Tubeezator on Mon Jul 08, 2013 11:51 am





These are the 1541 Mainboard [CD820] top side and bottom site in their original condition. Marantz CD40/50/60 use the same one too.

.....will be updating with some picture once after i have done the recap process,each caps is "tailored" for specific application and purposes. Like usual Naim`s trait, more boogie faktor, less fatique.

These are the original diodes extracted from the board,they are replaced by the bobbin type..Fast switching!


Diodes upgrade are optional,a very good exercise to your soldering/sucking skill. Shaky hand may breaking the tracks/joint.

As you can see, the board has recapped with various type of chosen "First league" army, they are very important,they are chosen to do very specific task,not a cross trained type.

After completed the recapping process, the soundstaging has improved 100%.It is like improving from previous 2D to present 3D.
