Well, if they are to be 75 ohms, and they read 2.5K ohms, and they are in series
with the filaments, then the current will be very low, and should not be a problem
at all if you fire it up..... tubes will not lite.... If it's a thermister and they drop
like said, when they get hot, then at 2.5k they are a pretty good safety cushion
for the tubes.... Better than 850..... might be smart to leave them alone.....?
Looks like a tv I just got done working on for my brother.... Bad electrolytics,
I saw those 2 resistors in the string, didn't even give them a thought....
Filaments come on slow, so I guess it's working as it should.....
