I am trying to assemble the Fuzz unit in Penfold's "Music Project" book.
It requires metal film resistors, all 0.6W, but I only have carbon 0.25W.
After reading here and there in the forum, I understand that the material of the resistors will affect the signal introducing noises.
But what about the power rating? Am I going to fry the carbon resistors?
If I understand correctly, power rating is the maximal limit for heath dissipation, that is how much power the resistor can convert into heat.
Now, if the pedal is powered with a 9V battery, 9V is also the maximal voltage applied to each component in the circuit. Then, according to Ohm's law, a 100 Ohm resistor with a power rating of 0.25 W will melt with a 9V voltage ( 9V x 9V / 100 Ohm = 0.81W). On the other hand, a 100 KOhm resistor in the same connditions will have no problem (9V x 9V / 100000 Ohm = 0.00081 W).
Is that correct?
