The best info I have is from
http://www.thevintageknob.org/YAMAHA/PF1000/PF1000.html#
which says it is a medium mass tonearm with 10mg friction (verse say 20mg for Systemdek Profile arm).
I am not sure how you would add mass. I had a Discwasher DiscTracker on the AC-2, adding +0.6g VTF and forcing counterweight halfway off to balance, but not much difference in sound.
The headshells are hard to find. One went on eBay for $5.00 not long ago (cannot believe I missed that). I finally spent 79 Euro to get one:

has grounded shield that I have not seen in brochures or manuals (which are available at Vinyl Engine). If you find a better source, please let me know.
