Vi segnalo questo articolo, in quanto la revisione dei ritorni a massa del dac e del cristallo suggeriti dallo sperimentatore, hanno molto a che vedere con l'efficacia che risultano avere solitamente i clock esterni.
Mi sembra assolutamente da non perdere. Le modifiche sembrerebbero molto più economiche dell'acquisto di un clock.
Qui, le istruzioni per disassemblare la PCB dal telaio:
I do have a link to a website that tells you how to take out the transport: http://iangclark.net/projects/CD63/CD63.html
It is about replacing the laser-unit, but it has some nice photo's of the transport.
Taking out the main PCB is not very difficult. Remove the connectors to the transport and to the front. Remove all the screws that hold the PCB to the bottom (seven pcs.). Slide the drawer out a bit to make some room, and release the mains switch plastic clamp with a screwdriver. Unscrew the three screws that fix the connectors to the back-panel, and now you can take the PCB out. Slide it forward a bit and tilt it upwards, and you can take it out.
If you are going to work on the PCB a lot, it is much easier to leave the metal back-panel attached to the PCB. That way you don't have to watch out for the connectors, and it's very easy to leave the PCB standing upright, on the back-panel. To do this, loosen the screws that fix the connectors a bit, but don't take them out. Unscrew the two screws at the left and right of the back-panel, that fix it to the metal side panels. Unscrew the three screws at the underside of the back-panel, that fix it to the bottom. Now the back-panel is loose. Push it down a bit to release the back-panel from the side panels and slide the PCB out the back of the player, together with the back-panel. Tighten the screws of the connectors to fix the back-panel to the PCB and that's it!
