""there is some intermittent noise during playback"" if it has tubes.. The noise is from a tube, not the laser

I Googled you model number and the images show the unit has tubes.
The 'classic' tube problem if they get old and are starting to fail:
"there is some intermittent noise during playback"
For preamp tubes (which IF you have tubes, they are preamp tubes) the real typical problem is they become noisy. IE start making some noise, but music still plays.

Whomever said replace the laser is not very smart about laser problems.
Lasers STOP WORKING, or you find it hard to start a disc, or the disc is always skipping..

But NOT noise while playing.. No way!! That is NOT a laser reading problem.
So IMO you should have a tube repair type person look at your tubes.
