I bought a cheapie turntable tonight at a thrift store. Hitachi Direct-Drive[Hey, what do you expect for $3.00? Actully, for $3 it is pretty darn nice.] Anyhow, this has an S-shaped tone arm. If I were to install a new cartridge on this table how would I do the alignment? Would I just use my regualar alignemt tool?
I am going to make an attempt at humor here and assume you do not mean something from Stanley Works, like a ruler or tape measure. Insert a rim shot here!
Real answer is: Yes.
Actually my alignment tool is a Turntable Basics tool. The same one shown on that page. I've never worked with an S-shaped arm before so I didn't know if I had to do something different alignment-wise.
You can't get much more for $3 than you did!
If you can align the cartridge in the Hitachi arm to a two point protractor, then you should do so. However, there were many factory installed "S" and "J" shaped arms whose length and geometry didn't allow a typical alignment. If this is the case with your new analog source, align the cartridge to the outer alignment point of your protractor and go from there.
