Sony CD player optical pickups
 
Anyone know how good the new Sony KSS-213 type optical pickups are? Any problems?

Anyone know an upgrade for an Sony KSS-210A type optical pickup.

I have a 12 yr. old Aiwa mini system with a three disk changer. Six months to a year after I bought it, the KSS-210A optical pickup went bad. I replaced it with a KSS-210B pickup after hearing how the original Aiwa pickups go bad. It served me well for almost 12yrs. and now has occasional tracking problems. I only noticed this on extended lenght CDs. I am going to inspect the motors and sled mechanism for problems. Probably needs to be cleaned and oiled. If it is the pickup, I want to upgrade it to something better. If it turns out to be something worse, I will have to consider a new stereo. I am interested in how reliable the newer type KSS-213 optical pickups are since they are used in newer Sony models.

The KSS213 series has been around nearly as long as the KSS150/210 series. Reliability on the KSS213's is actually worse than even the KSS150's. Strangely, the cheap old KSS150/210's are still one of the most reliable laser units ever on the market. A thousand times more reliable than the criminally crappy CDM12 series Philips garbage that too many people get stuck with, even by supposedly "high end" companies.
Note that the KSS213 is NOT interchangeable with the KSS150/210(which are interchangeable with each other), as it has an entirely different sort of connector.
Most of the problems with the KSM2101- series mechs in the Aiwa systems were due to teeth shedding on the tracking drive gears. Any loading mech that tilts the KSM2101 down & up, e.g., Aiwa, older Yamaha 5-disc players, and most other Sony laser'd carousel units, develop this problem. These can be ordered, last time I checked, from mcminone.com, but don't know gear part #'s off hand. It is, though, possible yours just needs the chrome tracking guide rail cleaned & regreased, or something else impeding laser sled travel near the outside of the disc area.

KSS-213 comes in A,B,C types. Not sure whats the difference.
The Rotel RCD-971 (mine) and the newer RCD-02 uses the 213C.
I get to buy the whole KSS-213CCM assembly for less than US$15 here.

Oh my post yesterday did not get into the database! I'll try it again:

I've got the same problem (see here . Cleaning helped a little but not too much. I still have some tracking problems in the beginning of a disc. My Teac CD3 uses a Sony KSM 2101 AAM with a KSS 210B laser. The only mechanism I can find in Germany which looks the same for a reasonable price is called KSM 2101 BAM.

Does anybody know if the KSM 2101 AAM and the KSM 2101 BAM are interchangable? Are there any better alternatives? There is no information on the net (at least I did not find it).

Best regards

The teeth on the sled drive system are not damaged. It could be that it cannot track a smaller track pitch (loses track position randomly on extendend play discs, plays regular disc fine), the sled motor is dying or the pickup is weak. If the sled motor is going bad, I rather replace the spindle motor also. Anyway, new assembly will be reqired. It's cheaper and easier.

Are the infared lasers used in cd pickups better than the red? The original pickup was an infared laser (KSS-210A) and was replaced by a red laser (KSS-210B).

In my experience, those "erratical jumps" are due to hardened oil/grease. The sled sticks a little and moves suddenly way too far, so the pickup can't follow the track anymore. Especially at the end of a disc and even more while playing the end of a very long disc, the sled moves on old grease, that has not been moved for a long time and has got really sticky.

Floric, try http://www.partstore.com for the KSM2101 mechanism you are looking for.

The KSM-2101AAM & BAM should darn well be interchangeable, if they appear very similar.
I have never seen grease binding problems on Sony KSS210/213/240 based mechanism. They use a light silicone grease that does not seem to have cementing tendencies like some moly greases used in other mechs have. I have, however, seen the ribbon cables that connect to the laser get routed slightly wrong & cause resistance to sled movement near the end of sled travel.
I have never seen wavelength differences ever noted before on different KSS210 series. I'd be very surprised if the laser diodes were't identical.
Best place I have seen to get Sony lasers & transports is dalbani.com, with dalbani.co.uk being great as well.

thank you for the answer stephensank, I thik I will give the KSM2101BAM a try.

If the grease does not harden itself, it is bound with dirt and dust. In my player, the last Millimeters that are not used normally were really sticky. But I have been a really strong smoker for some time.

Thank you

Floric
