I’m pretty new to this but I’m trying to put together something from a schematic (see URL) . I made a list of the components and took the list to Radio Shack. On items like the resistors, I was able to find resistors with the same wattage but not the same tolerance. My questions are as follows:
1. Are the resistors and capacitors in this schematic unusual so that I’d have trouble finding them?
2. Are the percentages on the schematic actually referring to tolerance or are they just showing overall signal change?
3. If I am correct in thinking I need to trace down a 6.8K Ohm with 1% tolerance, where is the best place to find such hard-to-get parts?
