Philips CDM-1 Mk2 replace by CDM-4 ?

Posted by Tubeee on June 14, 2003 at 06:51:20:
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...
