philips sacd 1000 repairs

I am beginning to experience a failure in my Philips SACD 1000.
From my searches on the net I find that my problems are not isolated.
It would appear that the problems centre aorund the following 2 ic's

SAA7399HL/M2A Digital Servo Controller "MACE2"


To my dismay , I find that these 2 ic's are now obsolete and worse, my local service centre does not even have stocks of the same.

It seems a shame to discard the SACD 1000.

Is there a source for these ic's ? COuld anyone here help?

Thanks in advance
