Due to age of these 60 yrs do you replace these wire resistors? One is a 4800 ohm the other is a 2600 ohm. One still reads as rated on Sams the other is a little off but within tolerance. I was thinking they would be hard to find if they needed replacement.

As long as they're not open and are within tolerance, I would leave them alone for the time being.
Others' opinions may vary.

I have never seen a wire wound drift in value,
only opened. Sometimes the shell falls apart &
IMHO should be changed even if OK. Finding
them should be no problem.
Keep in mind many sets use a "fusable " resistor in
the power supply usually 5.6 ohms 5 watt & you need to
use the right thing there.
