Hi Carl,
What size wire would you recommend for a 1A supply?  If there is a
choice of where to insert the wire would you use it in the RF
compartment or near the B+ supply?  Would you recommend a glitch
resistor?  If so what size, value and type (carbon, film...)? Thanks

It gets downright dangerous when the glass breaks and the small arc
becomes a monster plasma arc searching for paths to ground.

I think that's why HV fuses are in glass tubes, packed with sand.

Using a small wire as a HV fuse can also create a similar problem.
