I have just been cleaning and restoring the finish to the Technics SX KN 720 I bought for £21. after 15 mins work it looks new.
I can not understand why,when someone is selling something they leave it in a disgusting dirty condition. My Yamha was similar when I bought that. Apart from someone more likely to buy it if it looks good, but there is also the impression you give of yourself !
Anyway, now its black and shiny again and everything works.
Now I need a double keyboard stand (or 2)
