Hi All Pro:
I have a Philips CD880 CD player. I think the laser pickup is getting weak in strength after intensively use for years. I heard that since the cdm-1 mk2 is too hard to get there is a solution to change a brand new head. The solution is to purchase a CDM4/19 laser pickup and dis-assemble the pickup and take only the swing head mechanism and to replace the original cdm-1 mk2's swing head mechnism.
I then bough a CDM4/19, it looks almost the same as the cdm-1 mk2's. The only difference is that there is a 100K ohm resister beneath the laser beam in cdm-1 mk2 while the cdm-4 isn't. Can I just do this? Will this replacement kill/burn the servo system or I can replace but need to change/add some passive components on the servo board?
Need your options to go on...

The original CDM-1 as used in the Marantz CD94, 95 and Wadia WT3200 among others does have a modern replacement laser available in from an outlet in Spain if that's any use.
Best Regards,
Chris Redmond.

    Try Grandata in the UK. I have a CDM4 laser on order with them.

        If you're stuggling and they don't ship overseas let me know; I could order the laser and repackage it off to you.
        I'd estimate shipping from the UK to be $6.00 maximum - that's how much it costs to ship a CD in it's case anyway.
        Best Regards,
        Chris Redmond.

        Thank you very much Chris.
        You are so kind to response like this. Feel so good, however, I have checked and they are out of stock too....

        I've just been given a website to try out; www.partsonline.com
        Worth investigating.
        Best Regards,

    My mistake - the source is in Holland but I got the address off Orejones who is in Spain and has used the part himself to good effect; if you struggle fitting it I've no doubt Orejones would give the benefit of his expertise.

        I have contacted Doknet and they have none! I have a CD94 MKII which I have tweaked and have been trying to get a spare laser for. So far I have had no luck.
