@au_lait Can easily see how your Jamaican records got too much sun.
I said bin warped records you can't play. Warping is a matter of degree. If they are 'NOT THAT WARPED' then quit complaining and play them as you suggest - EASILY PLAYABLE.
What are you worrying about??
Anyway, my Aeroarm plays severely warped records no other arm will play. How? Because is is 1/4 of the effective length of a typical 9 inch arm and about 1/5 of the mass. There is always an answer for those who seek.
