No, that difference in the value of Emitter resistance would no be the cause of fuses still popping on you.
Actually it takes a darn good ohm meter and really short lenght test leads to read resistances under 1 ohm , or even under 1.3 ohms with accuracy!
I use my cap ESR tester to check things under 1 ohm
Most known manufacturer 5 watt wire round resistors these days are darn accurate, the 2 amps I am working on now use .47 ohm resistors and 3 tested out at .51 ohms and the 4th at .52 ohms.
Since your still popping fuses one thing to check that is easy to over look is that the metal cased bias diode leads are not shorting out to its hold down clip inbetween the output Transistors
