Lyra Delos suspension aging?

Recently I noticed that my anti-skate requirement had "drifted" (hadn't been adjusted for 2 years).
Found it hard to blame the tonearm because the weight is still at the same point that I set it to and positionally the thread controlling the pulley+weight looks equally correct and stable.
Other possibilities occurred such as relaxation of the arm wiring with settlement. (Arm was installed at the same time as the cart.)

Finally, I turned my attention to the cart's suspension. Has anyone noticed their cart in need of an "anti-skate reboot" over time? The cart has done less than 800 hrs.

Of course, AS could be a red-herring altogether. It's also possible that metallic debris may have been attracted inside the generator and ended up fouling the cantilever.

Theories?
Needless to say I'll be watching it more attentively from this point. Forewarned is forearmed. ;^)

Now that I'm officially retired I'll have plenty of time to investigate matters such as this :)
At the moment I'm listening to an old magnetic tape recording of a Genesis' live performance of "Twilight Alehouse" broadcast by the BBC on FM radio 40 years ago.
That track seems somehow very appropriate to my new circumstances ;^) :)

Hi Moonglum: If you have any worries about the condition of your Delos' suspension, you can send it back to us (preferably via the dealer that you purchased it from). We will inspect it, and if the cartridge's condition requires it, clean out any debris, and readjust the suspension.

kind regards, jonathan carr

Dear Moonglum:

If the anti-skate setting was too high or too low, it is possible that the constant side-force would cause the Delos suspension to take on a "set" after some time. When we ship new cartridges, we make the cantilevers as straight as possible, but when customers send us back those same cartridges later for inspection and servicing, more than a few have cantilevers that have become tilted to one side (although not all of these are due to improper anti-skate settings - undoubtedly some of these tilted cantilevers occurred because the cartridge received an impact).

It is also likely that some amount of debris has been gradually sucked into the vicinity of the generator coils, but if the Delos' tracking abilities remain similar to what they were when the cartridge was new, probably not enough debris has collected for it to be a problem.

Dear Moonglum: If you are now getting mistracking on albums that previously had no problems, there is a chance that dirt build-up has proceeded to the point that it is starting to foul the cantilever.

In any case, my suggestion is that you send your Delos back to us (via your dealer), so that we can take a thorough look at it and correct anything that may be amiss.

kind regards, jonathan

Hi Digital3: I don't know what the cost of a rebuild or exchange is for the following reasons: Prices are determined by the distributor in each market rather than Lyra. My strengths are in the field of engineering, not business.

My recommendation is to get in contact with your dealer and have him send it back to the Lyra distributor in your country, or if your dealer is no longer available, feel free to contact the Lyra distributor directly. It always helps us if you could include a short note with the cartridge, clarifying what you want to have done. For example, you could ask us to inspect the stylus, suspension and dampers for wear, and rebuild or exchange the Delos if the wear has proceeded too far; but if the stylus, suspension and dampers still have some life in them, that we clean and adjust the cartridge so that you can get a few more months of usage before actual replacement.

kind regards, jonathan carr
