you need a 100ohm resistor, all you have is 91ohms........
That's my understanding Chuck; that the metal film resistors produce less noise. I haven't done a comparison, or any measuring though, so haven't actually noticed it.

I measure all resistors before putting them in circuit, but checking on values after a resistor has been soldered into a circuit can be a nuisance if it's a metal film, as they don't always comply with visual checks and, as we all know, measuring resistors in-circuit usually doesn't go as well as it does with tube circuits. That's one thing about tubes that I like!
