Poogeing the SACD: The Pioneer 563A

The flexible harness are like any other flat cable/connector connection. They are usually soldered at one end and inserted into a connector at the other. Just pull out gently of the connector and they come appart. If you cannot move it, it is soldered!

Note: These flex cable connections are not designed to be removed often. Try to reduce the number of time you touch them, the less, the better. Don't get nervous thought, you can easily disconnect them 10 times or more without problem. Be very carefull when you put them back.

I dissassemble the supply, then the audio PCB. Then I disconnect the front Panel from the digital PCB and remove it. Finally, I let the transport and the digital PCB connected together and I remove both at the same time.

I used your parts list as a guide line. No I didn't change the diodes in the supply. This a switching supply and from my experience, the choice of diode in some part of the circuit can be critical. Without the original diode part number and specs, it can be adventurous to replace diode. The circuit can be easily degraded.

No I didn't ground the foil. In two of my good players, there is often foil on top of caps and IC (my Copland CD for example). So I did the same just in case...

Here my version of the Analog Supplies that I built into my 563A.

Hey guys, I have a question...
I would like to get a similar device and tweak the heck out of it. I mean the best I can.
So since I am tweaking it and all the stuff, would it be possible to add some digital SP/DIF input to the player? This way I would be able to use all the goodies inside(DAC mainly).
I know it sounds like crazy, but is it possible at all? If so, how big a deal is it to implement it actually?

does anyone have (and want to share ) the dv563 service manual and schematic?

thanks!

you guys are crazy!

I removed all relays, muting, etc,and basically DC'd, and zero ohm'd the output of my 563 with no problems whatsoever. I like playing with fire. I run my amps wth so much current and uf that if the thing goes into meltdown, the relay in the basement is the fuse at 20A..and the amp will still run 30 seconds after that, no matter WHAT has blown up,shorted, etc. I have had to run to disconnect speaker cables before.... disconnetcting them is my only fuse method.

Needless to say, I never leave the thing on while stepping out. Sounds good though.....

Hey KBK,

Sounds neat. Care to jot down a schematic of how you configured the system so we too could experimet.

I personally turn off my system by pulling out the tubes from my power amps. It's amazing how many burning kleenex I've had to stamp out under foot, but that's a small price to pay.

No AC switches on my gear. That would ruin the continuity of the electrons as they flow through the ether of the silver oxide in the cable.

You know the old saying attributed to Confucius (Kung-fu-tse).
To fuse is to confuse.

Cheers.

Guys,

I read the thread and found something writing 565A is almost the same of 563 model.

I'm going to buy a 565A, so I was wondering if someone could tell me for sure if 565A and 563 are the same player.

thanks!
