Hi
I’ve just recently changed a laser for the first time on my CD 67 using this glide took me about 30 minutes
http://iangclark.net/projects/CD63/CD63.html
Important steps to remember take care on build up of static will damage the laser
Check that the ribbon cables is full home the ribbon cable on the laser is deceiving it will go in further than you think you will know if this ribbon isn’t in fully as the disc will spin back in forth or anticlockwise
Hope this helps

Thank guy for all the help...

hi guy... i read the previous post regarding the skipping read error can fix by adjusting the Variable resistor near the laser head there...is it really help? where it located?

[Fidelity Audio]

Usually adjusting this variable resistor will kill the laser or allow it to work but it will have a short life.

if want to disable the muting circuit... is it just remove QN05,QN06,QN07 & QN08 only?...sound will improve greatly?

[Fidelity Audio]

I personally dont think removing the muting transistors makes much difference, it's just another tweak
