Default Re: 2W Carbon Film Resistors

Remember that the old carbon-resistors used in decades past were usually 10% tolerance at best - which means you can cut down the range of modern close-tolerance parts you need to stock.
The E12 series covers everything I've ever needed in terms of vintage restorations

1.0 1.2 1.5 1.8 2.2 2.7 3.3 3.9 4.7 5.6 6.8 8.2

I generally designed stuff so that if I specified, for example, a 3.3K resistor, the circuit would still function OK with a 2.7K or a 3.9K.
