Mechanical alignment is a huge problem as it can't be tweaked with the thing playing.
Knowing what we know now about the CDM12.4, I wish I saved all the "faulty" ones that techs replaced routinely.
Maybe an old player (like the Micromegas) that's original but being sold cheaply as faulty would be the best way to get a pickup that could be refurbished... as it was the grease issue that was the main problem with the originals.

This is indeed currently the only way, because nobody can tell me until this day the currently producer of the hologram laser diodes used still in currently available VAM1254/VAU1254 mechanism.
If I know a guy, whose mother language is Japanese or Chinese, and could perform for me some phone calls in China or Japan in this matter, I had figured out it certainly quickly. Correspondence in the english language with far east employers is very difficult.
Unfortunately the most diyaudio members from far east written here mostly their questions to get informations so as offers about their products, but don't written here for the dissemination resp. transmission of intresting informations from there
