I’m only guessing that Technics uses only billet high grade aluminum for the tables?
Heck, my use to be daily driver is the ’lowly’ 1980 Technic SL-D2 and I love this thing!
Reliable as all get out and every now and again all I have to do is drop some clipper oil down the shaft, that’s it. Not only is it perfectly flat but is a perfect circle also.
I'm with lewn too. You maybe able to get an uber inspected/gone through table, at a discount - for all your trouble. Doesn't hurt to ask.
