Trio Kenwood KD-1033 turntable main bearing service

  One of my first posts in this blog was regarding the servicing of the Pioneer PL12D turntable, and that has proven to be the most popular by a significant margin.

I use both names (Trio and Kenwood) as the company operated under different names in different markets.
