The easiest fix is to replace the swing arm assembly with a (working!) one from a CDM4/11 or CDM4/19, it's very simple to do. You'll then need to adjust focus offset and laser power on the servo board.

Hi,

Thanks for the repy's.

The CDM1 MKII is for my Radford WS1. I think one of this CDP players have all mechanism:

AUDIOLABOR 531 PCM1702 CDM-1 Mk II
EMT 981 PROFESSIONAL TDA1541A-S1 (Single Crown) CDM-1 Mk II
GRUNDIG CD 9009 2 x TDA1541A -S1 ? CXD1244 CDM-1 Mk II
KRELL MD-20 It? a Transport CDM-1 Mk II
MARANTZ CD75 Mk II TDA1541 A CDM-1 Mk II
MARANTZ CD-80 TDA1541 A-S1 (Single Crown) CDM-1 Mk II
MARANTZ CD-85 TDA1541A-S1 (Single Crown) CDM-1 Mk II
MARANTZ CD880J TDA1541A-S1 (Single Crown) CDM-1 Mk II
MICROMEGA CD F1 It? a Transport CDM-1 Mk II
PHILIPS CD-80 TDA1541A-S1 (Single Crown) CDM-1 Mk II
PHILIPS CD-85 TDA1541A-S1 (Single Crown) CDM-1 Mk II
PHILIPS CD880 TDA1541A-S1 (Single Crown) CDM-1 Mk II
PROCEED MRC100 2 x PCM58P CDM-1 Mk II
REVOX B 226 S / E TDA1541A-S1 (Single Crown) CDM-1 Mk II


So, i think i have to find one of this CDP and replace the plate that have the lazer. What do you guys think.

Before you replace be sure to check a 33uf bipolar capacitor on the servo board of the cd mechanism. They have a relatively high failure rate. This may be all you need. Also check all the solder joints-I repaired one of these by simply resoldering some bad joints. Good luck

Those small silver-coloured axial caps go flakey too.

It should work as long as your electronics are ok on your cdm1MKII servo board. As someone mentioned already you would have to adjust laser power & focus offset when you replace it. I've never seen 2 of these with the same laser power output.
