Ok so I took the module that I xrayed and made some measurements. I then did a little careful coring as to not damage circuit any more then needed to get the remainder of the info that I wasn't able to get with the bare board.
So with all my info patched together I come up with a schematic that looks something like this:

Now there could be a mistake and if you find one please feel free to point it out and I'll update the file.
Heres something I stumbled on while poking around. It seems ICM used different trim pots on their main board, don't know if it was what they had handy or what. But I have some with 100k trim pots and some with 50k trim pots, heck I even have one that has 50k trim pot on combustion blower,while having 100k trim pot on convection blower. I mention this only because the resistors are different internally for the corresponding trim pot. I have listed both part values, with the 50k trim values in parenthysis'. I measured the surface mount cap to be 97 nf which is more then likely 100nf with tolerence. One transistor is definatly pnp. I think the other is probably npn opererating in the circuit in a push pull configuration.
I also guessed on the top 1m(500k) resistor on pin 6 as I couldn't measure it. But it physically looks painted the same size and shape and a divider network makes sense there to me.
so there it is guys........... if someone can explain how it works I'm listening. I've also drawn out the main board but won't be posting that as it is something that you can do for yourself. If you can't then you shouldn't be messing with it in the first place as the high voltage can easily damage you or your equipment. Good luck!!!!!!
