I looked at upgrading my CD2 to a Linn player in 1998 but found that it sounded far better than a Linn Genki and a Linn Ikemi - only the Ikemi through the AA DAC sounded better to my ears.

I have just done a repair job on my CD2 which I use with an Audio Alchemy DDE 1.0 DAC (sounded better than the internal CD2 DAC system).

My CD2 suffered from the following faults (in this order) :
1. Display segments stopped working on the NSM4202A displays (after 2 years from new)
2. Audio output buzz (7 years from new)
3. Stopped reading CDs (14 years from new).

Have now addressed the faults:
1. I have located a source of new NSM4202A displays and replaced mine - though the new ones are green, at least they work!
2. Audio output buzz - put a scope on the DC rails and found sawtooth wave - essentially all the PSU electrolytics had failed (some were even being run over their rated voltage). Re-capped the entire main PCB with new electrolytics.
3. Stopped reading disks - found an article that said that CDM 2 and 4 mechanisms fail due to dried out electrolytics - so re-capped the whole servo PCB.

I use a Philips CD160 (NSM4202A display, compatible mechanism, and same chipset as CD2 player) as a 'test harness'.

I still have two dead DAC daughterboards - but at least the player works as a transport again. I plan to repair the DAC board 'offline' using my CD160 test harness, and provide it with upgraded Opamps, capacitors, DAC chips, and a dedicated super-regulated power supply (with totally separate supplies for the DACs and Opamps).

I may also uprate the master clock on the transport section at some stage - however now that I have it working as a transport I may leave it well alone for a while!

gdt, hi, I’ve been looking for the NSM4202A everywhere with no results! And I've been reading all over and it seems very hard to buy! Would you please tell me where you bought them? All the places I’ve found they sell in large quantities and I need only two to be shipped to Argentina. Any advice would be highly appreciated.

Thanks in advance, Joe.
