Hi All<br><br>I have on my lab. an ES-2401 Exploration Seismograph from EG&G Geometrics that is not working. I will appreciate if any of you have the schematics for this unit. The owner who is a professor at the university told me that their is not service for that model any more. But I will like to see if I can put it to work. I already found some of the DC/DC converters (power supply section) data sheet but I will like to have more details. If you have something about it please let me know.<br>
<br>Thanks in advance. <br clear="all"><br>-- <br>Juan Lugo<br>Tel: (787)833-8433<br>Fax: (787)265-1684<br><br>
