RE: Older Slo-Blo fuses have a small resistor inside

Posted by bugeyed on April 29, 2022 at 08:35:05:
These are all fast acting fuses.
So, I see that others are measuring some elevated value of DC resistance on low value fuses. FYI the 12A mains fuses measure .1 ohm. The 125mA fuses are in the self biasing ckts. of the KT88s. One post stated that it would not be a factor in a bias ckt. Should the fuses, at least, be all the same DCR?
BTW This amp is all tube KT88 output, 90W/channel in class A & is has a 12A fast blow fuse in the mains. Is that normal? The rec. value is not posted on the unit & I don't have a manual. BTW it is set up for 120V.
Thanks,
Kev
