I have recently assembled the K8060, and there is a problem with it. When i connect power, R2 is getting fried after a few seconds. I have changed it to a 1 watt, but it still doesn´t work. Any suggestion on what may be wrong?

Please check the numerous posts on this item.
Most likely, it is an assembly problem.

If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
