glad to hear yours is still working. if you squeeze fast enough it will probably click but clicking is an indicator of squeezing too fast. slow is good.
a record just taken from the tt can be alive with static. if you encounter one, do the process of squeeze and release (i usually release away from the record) and see if the static is gone. if so, GREAT.
if yours seems not to work as my 1970s zstat did, peel the label from the base of the pistol, remove the philips screws, and look for where the setscrew is on the crystal. it can be ever so slightly tightened and the zstat works again.
of COURSE they dont tell you, they would like you to buy another one. not necessary if you follow my instructions on that.
i also have another that a friend gave me so i had nothing to lose. but then if yours doesnt work, what is there to lose?
