New tonearm for AR XA: suggestions?
Hi all,
my trusty old AR XA turntable (purchased in 1970) needs some refurbishing. In particular, the tonearm is so worn out that I just can't get the adjustments right any more. Now, I found some nice L.A. Audio File articles from the 80's about modifying AR's: http://www.laaudiofile.com/backissu.html The last article has excellent instructions for choosing and refitting a modern tonearm. Quote: The preferred tone arm for the AR mod is one that mounts via a threaded pillar with a locking nut. Both the Mayware Formula 4 and Grace 707 Mark II meet this requirement. Unfortunately, my classic favorite, the SME 3009 Mark II Improved, does not. The springs on the I-bar subchassis are carefully spaced equidistance from its center of gravity. So, ideally, the replacement arm should be the same weight as the original. I found that the original tone arm and its spindle well (after removal) come to about 7 oz. Ideally, the replacement arm and its mounting plate should come close to that figure. Another important specification is the tone arm length - the original arm has a 9" stylus to pivot length, and is 11 5/8" overall. You should, of course, be sure the counterweight of the replacement arm will clear the corner of the dust cover. The problem is, since the article is 15 years old, both of the two suggested tonearms are quite hard to find (and expensive!) nowadays. I'd be grateful for any suggestions for other suitable replacement arms, preferably cheap ones... or, at least ones with good value for money. :-) -- Antti |
