Probably an easy question for all you guys but thought I should ask anyway so I dont get zapped or blow the monitor. Should I remove the monitor chassis from the monitor and remove all the excess charge if Im just going to be changing a pigtail fuse? Its a wells gardner 25k5515. I think that this is the only problem with it and thought I should try. Thanks for all the help.

You don't need to discharge the tube (unless you cant replace the fuse without removing the chassis+anode wire, which then of course you need to discharge the tube) but you certainly better check to see if the large filter capacitors on the chassis still have a charge (typical if a fuse is blown and it has recently been plugged in to test.
The simple test it to take a multi-meter and test both sides of the fuse when set on 200 VAC. Is there any voltage across the blown fuse? If so, you can bet there is a charged capacitor somewhere. If not, then double check voltages across the larger capacitors, and if not, then it's safe to work to desolder and replace the fuse.

Thank you so much, I will try that in the morning. Ill let you know how it goes, Bill
