Hi,

Have you tried replacing the the headstage, electrode holder and pipette
with a simpler arrangement of a metal rod with a pipette epoxyed at one end?
Does it drift in the same way? If it does not, the drift could be coming
from your electrode holder. This can happen if the the O-ring(s) in the
electrode holder are worn out. Sometimes it also happens with an old
electrode holder. 

Good luck,
Medha
