I did manage to find a picture of the front. I have one of these as well! And I had the same problem with the missing front panel..
I'm working on the schematic, the jpg is too big to upload here... So here's a link to the schematic I created..
It's a work in progress, but pretty accurate so far.

I hope that helps you out.

EDIT: This is actually the Typhoon 150 schematic. Sorry for the mix-up, but I imagine the front panel would be pretty similar.
