Agree, if a tube tests a little "weak" and has no other problems and works in your set, use it. Sometimes mismatched output tubes (when the set has no bias adjustment control) can cause some hum and distortion, but they have to be pretty far off to cause any problems. Small signal tubes that test weak will mostl likely either work OK or not.
