Fat One Amps

No. Great vintage tone comes from the designs, major components used, building techniques and careful attention to detail in assembly. When these vintage amplifiers were originally being built, carbon composite resistors were what were available in cheap quantities, so they were used. They came with some undesirable characteristics: 20% specification tolerance from unit to unit, noisy operation and characteristics varying with different voltages. Metal film resistors can cost less than a penny each, can meet a 1% specification tolerance, are smaller, and generate less noise. If Leo Fender were still building amplifiers today these are what he would use.
