Hi
Normaly the CD shold work with the new caps. Recheck the polarity of C 2103.
Maybe you have to readjust the laser current.
Could not find how to in the Beocenter 9000 SM but similar in the Beocenter 9500 SM page 5 14.
On page 5 13 you’ll find the points where to connect the DVM. Measure 50 mV and adjust with R 3106.
Carefully turn the pot, the current changes quick in both directions.
Kind regards
Christian
