all the 125 V across it & it lights normal but fuses wont blow.
2) trouble shooting aid. Some sets like GE used one of the
white caps instead of five. If it opened the HOT will blow in
milliseconds. Other things also could. you usually WILL NOT
find the bad cap with simple test equipt. The bulb trick allows
you to "unload" one thing from the FBT at a time till you
get a dim bulb with some HV.

So the four replacement HOTs are safe. No need to sacrifice any of them. I'm still am glad I bought 4 of them. At $3 each and $4 shipping, it's well worth having some spares.
