Just curious as to how you're implementing the HV fuse on the HV XFMR secondary 
to prevent it from blowing during the initial inrush of the filter cap charging 
(assuming C input).  Obviously, step-start in the primary is going to be a big 
factor but is that enough to keep a useful size fuse from blowing during the 
initial inrush?
