I keep on ordering supposed 1% tolerance 1 ohm metal film resistors, for the purpose of having an easy bias measurement on the cathodes of my fixed-bias amps. However, despite the fact that I've ordered these several times, they never end up actually measuring 1 ohm on my meter, usually more like 1.3 to 1.7 ohms. Is the problem that the resistor is not actually 1% tolerance, or is my meter likely inaccurate at that small range? Not knowing which it is is annoying, because I never know if I should adjust for this and divide by 1.3 when measuring the bias. If the resistors are bad, can anyone recommend a reliable place to get 1% tolerance 1 ohm resistors?
