Would just like to share simple modifications I did with my LG DK130 DVD player.
The reason I did this is so I can maximize my DVD player both for watching movies and listening to audio.
The modification I did are as follows:
1. Placed Flashing Tape on the transport and Duct Tape on the top cover to reduce vibrations and improve low frequency response.
2. Replaced the RSM Output Coupling Capacitors to improve clarity.
Here are pictures of the DVD player![](http://i33.photobucket.com/albums/d87/rascal101/dk130_front1.jpg)
These are the tapes I've used
Here are the modifications on the transport and top coverDVD transport

Note: I am unable to use a thicker tape as this interferes with the DVD transport and push it downwards. In fact, there are indentions to the tape duct tape already after I screwed the top cover to the chassis.

Zooming into the Output Coupling Capacitors used (it is using RSM 22uF/16V capacitor; the brand is relatively unknown)

Note: The Lelon and NCC capacitors are connected back to back configuration (so that it can be non-polar) with the Iskra and Mylar capacitor connected to the Lelon and NCC capacitors in parallel. hehe ... I may have to rewire the highlighted NCC cap (color brown) very soon as its - pin is connected to the + pin of the Lelon cap (color green). It should be + pin of the NCC cap connected to the + pin of the Lelon cap.
Thanks for looking
