Mike Pranka graciously supplied replacement arm cup silicon and new belts w/o charge.
Once received I proceeded to go through the table by disassembling it completely, cleaning everything and then carefully rebuilding following the user manual's directions.
I am glad to say that all is well and my WTA is working as well or better than ever.
I've determined that the problem I experienced was actually due to dreaded "user error" and that there was no fault with the TT whatsoever.
Caveat: When in use be sure the supplied digital VTF scale is set to read out in GRAMS (g) and NOT in CARATS (ct).

I may have misdiagnosed the problem and have a possible solution on the way.
Frank Denson and Mike Pranka have been very responsive and extremely helpful.
Will report back.
