Interesting. I have to say, even though I have had two SL-1210 Mk-IIs for the last 20 years, I don't think I have ever adjusted them much apart from spinning the rear counter-weight if I noticed the needle skipping when I tried to "scratch". Think the cartridges are standard Stanton ones.
I don't even remember if there were any instructions supplied with these SLs on how to set them up correctly - don't remember ever reading any anyway.
I must use your instructions/tips to set them up correctly some time, I like the alignment printout trick, but it's a pity there's a need to have to buy that needle weight thing to get proper weight - should be included really, but they do have weights or numbers at least written on the counter-weight - may be sufficient.
