Could not find any schematic for ilssan model ISP 120SI

When I searched used
http://www.google.com/search?as_q=il...images&as_st=y
but also found No ilssan schematics.

I doubt if you're going to find the specific schematic for a Ilssan
whatever. Open the case, and identify the regulator chip. Then, dig
through the mess of schematics that Google finds and see if you can
find a similar schematic that uses the same chip. You won't get the
exact schematic but it will be close.
