- I presume you mean 4.7k, rather than the 4.7 ohm implied by your
- numbers. Aside from that, the fact that the specified value is 4.75k instead
- of 4.7k means that a 1% (or better) resistor is to be used. The 4.7k
- resistor could be anywhere from a 5% to a 20% tolerance, so - worst case -
- you could have a value up to +/- 0.94k (940 ohm) off from what is marked,
- compared to +/- 0.0475K (47.5 ohm) for the 1% resistor specified. The fact
- that the resistor was specified as 1% implies that the circuit *is* that
- sensitive. Nobody uses 1% resistors where 5%, 10% or 20% would serve - at
- least if *they're* the ones paying for the resistors. :-)
-
- If you actually used 4.7 ohm, instead of 4.7k, the results would be
- that much worse. (What's three orders of magnitude among friends? :-)
-
- Go thee hence and get the proper resistor. Try it. If you *still*
- have problems, take two asprin and go to sleep. :-) Then we'll try again.
-
- Good Luck
