Hello all,

I am trying to find a resistor for a guitar amplifier head that I have. The resistor got broken while going through some other things. The color on the resistor is BROWN, RED, VIOLET, SILVER which I looked up to be 120 mOhm 10%. I have looked high and low and far and wide online but haven't been able to find where I can get one. Can anyone help me find a place to get this?

Hello,

It would be nice to know in wich country you are.
That way we could give you a more localized advice.

Did you have a look at the big companies like Farnell / Newark, Mouser and Digi-key?

Does it matter if the tolerance is 5% instead of 10%? I am located in US. Thanks for the first post.

Hello,

When a 10% resistor is used, the circuit would work fine with a 5% resistor as the tolerance is within the limits.

That should be 12 + 7 zeros 10%=silver
120,000,000

Which makes it 120 Megohms

m is milli; 1E3
M is meg 1E6

which is quite high. 120 Meg ohm's is probably not in the range of most multimeter to be able to measure.

Sometimes colors are not clear.

Hello,

Do you have the schematic where the resistor is used?
As KISS already said, the colors can be difficult.
A 120 Mega Ohms resistor is not very often used.

120 megohms seems an unusually high value? You will have to take great care in mounting it, otherwise leakage conductance via the support or air humidity could drastically reduce its effective value.

Very not likely that the real value is 120 Meg. Probably a color distorted by heat.
Photo, please...or a brand name or a model number or the country you're in...

My colour vision is poor, but that violet looks blue to me :). Even 12 meg isn't a particularly common value.
