Are there any other (mosfet)heaters on the oven cavity? Seems that heating from one point is going to create a large temperature gradient which would probably effect spatial phase congruency. I believe this problem exists on the two mosfet configuration as well. Anyway, my idea is to remove the mosfet heaters, wrap my own heater using light gauge nichrome (aka, fuse wire), mica insulator and build a proper heater/oven assembly. Finally, pot it all together with some sauereisen ceramic cement. Nice, clean, controlled gradient.
Maybe I'm over thinking the whole thing too. I guess I'll find out when I start my experimenting.
