I open this thread for to talk about this kind of laser pickup experiences.
My experiences are not good. Main problems are:
-. Fungus.
-. Prisma moved due to corrupted glue.
Laser usually to be in well state. I've found one bad due to a bad repair.
This laser pickup perform is very bad, even when is new. I've repaired one with a bad laser diode. I have some that the reparation is not enought, because RF is very bad.
So, the last chance is to do a Frankenstein. To place a KSS-210 or a Optima-6 and to adapt. Is a good challenge.
The main problem is that all laser pickup I've seen, are with M laser diode, and OPH uses a N laser diode, so APC(automatic power control) is not compatible, and is more problematic, more work, more stuff...
So. I ask to the forum members, do you know a laser pickup, with a photodiode detector with diodes, that uses a N diode?
The ideal is that can fit, not to be difficult to find, and cheap, off course.
Another thing, the invent I did for to replace the laser diode in KSS-272a and similars, does not run well for to replace laser diode and adjust OPH laser pickups. You find a lot of moments that you think you find a good adjust, but then doesn't work. However, a good OPH shows a good RF signal. I don't know what I do bad, thre is some trick that I don't realize for to adjust. So, I give up and I'm gointg to try a "Frankenstein".
