atp-12t, at-1503mkiii tonearm interchangeability

[illini]

I have been reviewing the specifications for the Audio Technica atp-12t and the at-1503mkiii tonearms and the biggest difference I see, besides the improvements implemented in the latter's design, is the overall length; the atp-12t is 357mm while the 1503mkiii is 330mm.

I have a plinth designated for an atp-12t and I would like to know if the at-1503mkiii is truely interchangeable with the atp-12t.

Anyone?

The ATP 12-T is a 10" tonearm. The AT 1503 Mk III is a 9" tonearm. Some alterations in your plinth will be needed to align correctly. And you may need wood filler to cover up the old hole. And a little bit of paint work. But doable.

Thanks, sounds like the atp-12t is the one I'll hunt for...

The ATP-12T is a nice arm anyway. If I were headed to a 9" AT arm it would be the 1009. I liked that one a whole lot.

The ATP 12-T is a 10" tonearm. The AT 1503 Mk III is a 9" tonearm.

Both have an effective length of 257mm, so I'm wondering why one is 10"and the other is 9"?

 

[KentTeffeteller]

There is a effective length difference, see OP.

Well, the effective length for both is 257mm and I'm assuming that's more important than the overall length. The overall length of the tonearms is different, though.
