In a bit of a similar fix with a newly acquired 505 that came w 1 x small sub arm counterweight. Have some emails back and forth w Dyna USA w factory not having any 505 parts. Have inquired about using 507 counterweights….. no answer yet as I expect Japan involved. @dover , et al any help appreciated. I am so enamored w sonics w a NOS Signet TK-9 that I am contemplating pulling my Kuzma CAR-40 off the Triplaner to try on the 505….. but no way to balance it short of blue tac and quarters….
Lew - thx for the inputs on headshells.
Any help appreciated
