This is a question from a different Chris.  I recall reading somewhere 
about fusing the HV secondary of  power transformers on tube equipment, 
to protect against filter capacitor failure.  There must be some 
quick'n'easy way to calculate the size of the fuse for various 
applications, but for some reason I'm drawing a mental blank right now.

I also recall seeing somebody suggest placing a standard small lamp on 
the CT of the secondary, to serve as a fuse. 

Does anybody have suggestions for either one?
