philips cdm1 pro and cdm4/11

LeoJar · 11th October 2003, 04:29 AM

Hi
Anyone here know that if it is possible to replace the laser head of CDM1 pro with the CDM4 head? It is too hard to get the CDM1 pro for my cdplayer....

Thanks in advance
Leo

I think you are asking CDM1-MK2
I have posted the same question before but got no response.
Hope anyone experienced and willing to share.

I read you post too. I had checked the appearance of the laser head of Cdm4/11 and Cdm1 Mkii and they are too similar in sharp and size... I will try by myself but no sure it is ok or not

Cheers

On a related topic, is it possible to replace the CDM 2/29 with the CDM 4/25?

Leojar, tubee

Have you managed to replace the laser in the CDM-1 MKII with the laser from a CDM-4/19? Does it work?

Dr. H,

As I know, there are at least two model of CDM4/19. The one which has "composite" engraved letters up on the body sometimes does work.

The one which has "composite" engraved letters has visually identical main opictal head (end of swing arm) with CDM1 MkII.

Really need more data sheet or spec to go on....

I notice mention of the Philips CDM 4/25 laser. Does anyone know a source for obtaining this item, or how to start looking for one? Thx

I exchanged the laser/arms from CDM4/19 to CDM 1/MKII and it works.Also laser/arm from CDM2/10 works as a replacement of both CDM 4/19 and CDM1/MKII (even though it looks diffrent) I suppose all the CDM 2 and CDM 4 family have the same laser/arms.But usually two pots (22K and 4,7K) have to be readjusted to the new/diffrent laser.

Hi Zygibajt

I red the thread with deep interesting. I have Philips CD304mkII with CDM-1 (???) and I wonder if the pick-up would be replaced to CDM-4/19 pick-up it would be work or not? Could you give me any advice in this matter? Maybe you have any experience in with it?

Thank you very much

Regards
JKoch
