[Amps] high voltage fuses

[Fuqua, Bill L]

Perhaps I should have said return rather than ground.

Not a good idea. The HV positive does not want to go to ground, it wants to
go to HV negative.  In nearly all amplifiers the path from ground to HV
negative is through the grid meter. Check your schematic.

If you surround the fuse with a conductive tube, connect the tube to HV
negative, not to ground.
