My mono table is from 1976 - Technics SL-1300MK2 (the cuing arm and lift all fixed).
My main table is Luxman PD-171 from 2002. The tone arm was upgraded to Jelco TK850S.
Unless either of them break, i will probably never replace these tables.
How often do you upgrade turntable ?
The table itself, not arm or cartridge.
And when you do, how far do you go ? Big steps, small steps ?
I got my Nottingham Spacedeck more than ten years ago and have no intention to replace it. I would have to jump high for the upgrade to make sense. One day perhaps.
