Actually, it isn't as bad as spiregrain
suggests. 10% resistors are not easy to find nowadays
, and they actually use a different process for 1% resistors. 5% resistors are usually pretty close, and you will occasionally find one that is as close as 1% in the 5% batch.
It has more to do with the economies of scale
than 'the man
' sticking it to you yet again
. It's cheaper
to make resistors using the 5% process, and they are in much higher demand than 1%. But the 1% process is getting sufficiently cheap that eventually the 5% will go the way of the 10%.
