What resistor do I need to bump the KL1 to 550mah?

I want to bump my KL1 up to 550mah-ish but I need to know what value resistor to get and where to get them. Can I get them at radio shack?

In post 5 of this thread, someone seems to think the stock bias is 500 ma:

As far as resistors, they are probably 1210 or 0603 size, and not available at radio shack. Once you figure out what value you need, I may have a few I can send you. mine are 1210 size, 0.1 and 0.47 ohm. Otherwise, try digi-key.com.

Ok cool. Do you know what current draw I would get if I got one of those .47s' from you?

No, I do not know what adding a .47 ohm would do to the draw. Do you have the head open yet? If so, what is the value of the resistors that you can see? They will probably say 'R47' or something like that.

It says R68.

Ok, that seems to mean that its a .68 ohm resistor, since the R47 is a .47 ohm one. If you stack a .47 ohm on top of it, I think it will make the overall resistance about .28 ohm. If you want to half the resistance of the resistor, you stack another of the same value in parallel on top of it. Its roughly adding the values together then dividing by 4, in this case. To calculate the equivalent resistance yourself (the total resistance offered to the flow of current) we invert the values and add them. Then we invert the result.

What this would do to the drive level, exactly, i'm not sure. It will definately increase it.
