Philips CD880 / CDD882 oddity

xtofhuygens · 07:33 AM

Hi,

I have picked up a hybrid between a CDD882 transport and CD880 player.
Pics on http://people.cs.kuleuven.be/~christophe.huygens/882-8801.png
Serial number is 990007. This looks like a factory proto of some sort:
- 880 board has 1541A in stead of 1541S (but original soldering everywhere)
- many mods on the mainboard, more than the stock 880 (early EPROM)
- CDD882 housing but no volume pot obviously
- 4 drilled holes in back for analogs out

Sounds and works great.
Members of the Dutch group (as well as my father in law who was a Philips
engineer at the plant at that time) seem to think the mods are factory original.

Any thoughts?

Thanks.
Xtof.

PS: I d be interested in the 882/880 service manual...

email removed please pm

- thanks.

Hi Xtof,

If those red cap's are from ELNA than (probably) it's original ! If those are from Black Gate, than 100% sure it's not done by Philips.

I have the original (paper) service manual but don't have the time now to make any copy for you. If anyone has it in PDF than it'll be much easier for you.

Groetjes,

Those red caps are not BG (the markings on the top are elna). I'd say they are elna Cerefine which were used by philips on high end models. They were also used in the early Marantz SE through to KI. The changes on the CD65 to SE were that all the PSU and some decoupling caps were changed to Cerefine.

Rubycon (inc BG) have K in the metal
Elna have -(-
Sanyo have Y
Panasonic )-

There are others but I cant remember them all.

Interesting that they never seem to worry about changing any of the local decoupling caps in the digital domain!!!!

Not sure what those additional yellow jumper cables are for and I cant see the pin config for the XC86HC24P chip to see what that pins for.

Thanks -- on the 68HC24 the yellow wire is connected to the reset pin, maybe a later version of the software resets the PRU in stead of power on reset, since it looks like the 68HC24 is connected to the CPU now. Xtof.
