Krell KAV-250CD mk2

eradoncic · 09:22 PM

I bought recently second hand KAV250CD mk2, which works very well.
I cleaned the lens using a standard cleaning comercial CD cleaner, and almost immediately after that, I noticed sometimes the CD skips, no matter if it is new or old, printed or recorded.

This made a suspicion to me, that maybe I should change the pickup (or anyway to have one to spare), but I cannot find any information which model is. Asked Krell support, but they (as expected) are sugesting to buy from them, for 200$.

Does anybody have this kind of experience, and does it anybody know which laser pickup unit is inside this model?

Any input appreciated

My records say it's a CEC mech with a Sanyo laser that's all, no model no's. I know the KAV-300cd has a KSS-240A laser.

Cheers George

Wlell it is not C.E.C...it is some older Philips, ECOSL mk3, or something.
Krell sells it for 200$ from the service entrwork, but I did not understand - only laser pick up, or whole trransport? It seems a bit too much to be only pickup

The KAV300CD has the Sony KSS-213.

Hm...I don't think so, according to some internal pictures, it seems like some of the VRDS/TEAC transport in KAV 300CD

Confirm CMK4 but I beg to differ on the laser pickup. The laser unit is the KSS240A. I also have the KAV300CD and have just replaced the 2-step tray gear and also adjusted the focus and tracking gains. (see TEAC vrds T1 gear broken thread) Unless of course the laser unit used is dependent on mod number.

And the lesson here is that you should NEVER use a 'lens cleaning cd'.
Those little tassles are known to damage laser pickups and there alignment.

If it is a Sony pickup the lens suspension has probably failed, you usually can tell this if the lens is sagging in the pick up assembly. I have managed to save a few by heating it in a low temperature (inverted) for a few hours and normalizing the temperature slowly. This might work but not always.
