Hello.I have this old vintage cd player Denon dcd-520. I fully recapped it and removed the 2 muting transistors it had and now theres only a small audible pop during power on and off but its ok.Original Laser is KSS-150A.It reads well all original cds and all cdrs but not CD -RWs. I had a cheap KSS-210A bought of ebay and gave it a try.it worked out of the box.I dont have an oscilloscope.
I raised the laser power by turning the trimmer a bit and now it reads CD-RWs.
Does anyone have a service manual for my model?
How to know if the increase of the current is within specs of the laser so as not to destroy it or destroy any other part on the main board?
The opamps it uses for audio are 4 pieces NE4558.I installed IC sockets there.I also have NE5532,TL072 (4 pieces each) and 2 pieces OPA2134.What do you suggest to use?
