Hi, I'm about to put a simple 10x or 100x pre-amp onto my 4.5 Hz geophone which I recently got from the Group-Buy. What sort of damping circuit should I put in front of the amplifier to prevent the geophone from simply oscillating? Also, what attenuation would this represent? Sorry if this has already been covered. Cheers Ian Smith _____________________________________________________________________ Public Seismic Network Mailing List (PSN-L)
