Philips CD-Players of the first generation

The CD is dead - long live the CD!
Here I will share my 10 years of experience with the Philips CD-Players of the first generation. Step by step I will modify a CD104 in one of the best CD-Players in the world.

1. Stroke: Power supply board

With this modding, the player gets new juice. At least twice the capacitance of the original capacitors and even three times of the capacitance for the so important 5V digital supply.
Furthermore it gets an excellent Furutech mains socket to make the player securer and get rid of first weak design points. Also i will fix the fundamental audio theme called: ground loops. I found 6 ground loops.

2. Stroke: Laserprint

Here I deal with the other end or more likely the beginning of the digital signal! The laserprint houses the control for the laserdiode on one hand. The laser has to emit light as constant as possible. On the other hand it comprises the amplifiers for the signal that is obtained by light interference. This signal splits into the actual data stream that is being demodulated to the digital signal and the tracking and focus information that is being evaluated by the servo. A good summary of these complex operations is on Wikipedia or even more detailed here.
When this tuning is performed, it is a good opportunity to clean the shaft of the drive and replace the platter bearing with Teflon. If you order "built in your player" I will also clean the inner lenses of the laser stock. This cleaning is necessary due to after 30 years some debris has fallen through the moving focus lens.

CD - Tweaks

Some things get stuck with you. In High-End and the rest of your live this is a clear sign that something is working. Three tweaks so far that imho definitely bring better sound:

CD washing machine

CDs are clean, when freshly bought ... or not? Since years I use the CD washer "Hydrobath 1120". Here little Youtube-video how this works.

Blacken the CD edge

All you need is a black Edding 500 or similar waterproof felt tip. If you want to take it exactly, you can also blacken the blank area on the outside which can be easy observed under some LED-lamps.

CD-mat

to be placed on top of the CD ... I use this one.
