Thanks Stephen, that is useful information. I guess a lot of these have been junked over the years when they could have been easily repaired, because it was automatically assumed to be a failed laser. It is a shame that the myth that a laser wear out like a stylus does still gets propagated. A lot of good players gone to the tip due to that.
Do you have a link to the replacement switches?
