I found a couple of good articles that may help, one on refurbishing the AR,
the other on modifying.

I just bought an Acoustic Research XA Turntable on ebay to fix for my own
personal use. The turntable is missing the headshell and the stylus. I
have
been told that AR TT's use an exclusive headshell that cannot be replaced
with other brands. This means that I will have to either find an AR
headsheall or change the tonearm. Does anyone have advice on changing the
tonearm on this table? Or does anyone know where I can obtain a headshell
that will fit on the AR tonearm?

Please help! Thanks,
Nicole.
