No you can not replace a KHS-400C for a HD7 or Sanyo laser in any version.

Your coil mesurements are ok, they seem high but should be fine. They are normally around 5-6 Ohms but as long as they arent under 5 your fine. The high measurements might be from your meter not actuall reading zero ohms when the probes are crossed.

That chip you linked to is only a partial replacement. Look at this http://www.richspsxparts.com/v9.html scroll down to the "LA6508 CLONE" this is a complet replacement. Or you can get an original Sanyo driver IC http://www.darkplanets.com/product_i...ype=4&prod=169 but you would only do this is your LA was fried to begin with.
