What alignment method? Audio Technica ATPL120

I couldn't get it to work :(

A better question is: Can I align the ATPL120 using Baerwald? Does anyone know, is this OK (as in it won't damage my vinyl)?

If it were my turntable, and especially if I established that the effective length of
the PL-120 is the same as the SL12x0, then I would definitely just use the
Technics protractor available on VinylEngine.

What kind of cartridge are you using? I don't think there's much chance of
damaging your records from incorrect overhang unless *maybe* you're using
one of those extra long, thin stylii, such as a Fritz-Geiger. If it's a basic elliptical
or MicroLine, you're probably safe, and if it's conical, you're almost certainly
safe.

By length, do you mean mounting distance? What exactly is mounting distance; how do I measure it?

Technics or Baerwald (or both) is the ultimate question...

For best alignment, Google Mint Tractor and they will custom build you a mirrored, very acurate alignment tool specific to your arm and table. I find this device far betters all the others.

I've scoured for equivalent specs for the PL120, including the downloadable
owner's manual, but AT has nothing to say about effective length or
overhang.

On the Technics, effective length is 230 mm; overhang is 15mm. Effective
length is the distance from the tonearm's pivot point to the stylus when
properly aligned. For overhang: Swivel the tonearm to the spindle; overhang
is the distance between the center of the spindle and where the stylus should
be when properly aligned.

Therefore, on a Technics, the distance from the tonearm pivot to spindle
center is 215mm, and the overhang is an additional 15mm for a total
effective length of 230mm.

Measure your tonearm from its pivot point to the center of the spindle. If it is
215mm, you should get an excellent alignment from the Technics protractor.

And really, it's a subjective thing anyway. To align a cartridge, you have to
get the overhang to where the stylus hits the groove at a 90 deg. angle at
two points, called null points. Different alignment methods go for the null
points at different places along the record.

The thing about the Technics alignment is that it favors (so I've read) a more
accurate alignment toward the inner part of the record to minimize one of the
LP's more noticeable weaknesses--inner groove distortion. There should be
less of that with the Technics alignment. It works for me.

Oh, and since the Ortofon Blue is an elliptical stylus (great matchup, btw), the
alignment is going to be more forgiving than something like a Fritz-Geiger.

Either alignment should work OK. The downloadable protractors are free.
Try'em both and see if you notice any difference. I favor the Technics.
