I received two days ago my G3 Blues kit and first thing I do before starting is checking the Bill of Material. Everything's there except 3 resistors are pencil-marked with their supposed value, but the color code and my multimeter says otherwise : R3, R19, R21 should be 68k (blue-gray-orange-gold) but are instead blue-brown-black-red-brown, so should actually be 61k and that's exactly what I read on the multimeter.
61K is only slightly off the 5% tolerance of a 68K resistor so I guess they should be acceptable and they have been voluntarily put in my order as replacement for unavailable 68K ones, but these resistors are connected to tube pins which are measurement points. So my questions are :
- Am I right to assume that 61K resistors instead of 68K ones shouldn't affect the functionning of the amp ?
- If answer to 1st question is yes, how will it affect the voltage in the measurement ? If it's outside of the given range, how do I know it's still OK ?
