I am repairing a tube amp & there are fuses in the bias ckts. for the power tubes. (KT88s) The fuses (125mA) that survived the failure measure 3.4 ohms & new fuses measure 6.6 ohms. BTW I measured the fuses with a 22 ohm resistor in series. I don't have instructions for adjusting bias on this unit & am concerned about replacing some fuses with these new ones. I didn't notice, when I ordered the fuses but, is the DC resistance in the spec? So, should I be concerned about this variance (3.2 ohms) in the new fuses?
Thanks,
