-- Hi guys- Philip, am I right in understanding that what you are saying is, just use a screwdriver, with well insulated handle, alligator clip, wire, alligator clip to ground lug on SE/30. No resistor. What gage wire is safe or is it just insulation thickness that counts? Forgive my lack of electrical knowledge. Jeff, thanks for jumping in. I think and hope that all this input is helping those of us who are electrically impaired, get a more complete understanding of the care and knowledge one should aquire while working around the CRT. -- Compact Macs is sponsored by <http://lowendmac.com/>.
