Tolerance resistors R5, R6 & R7


#1

The resistors 680 ohm should be 1% tolerance with the rings blue-grey-black-black-brown. These are not in the set but instead resistors of 5% tolerance (rings blue-grey-brown-gold).

Is this a problem for the precision of the readings when the scope is ready?
What will be the difference for the readings with the scope?
