Rufus, I'm confused. The baby blue fixative visible in each of the holes under the pan appear to be some sort of non or semi hardening fixative either exclusively for adherence or a combination heat-transfer and adhesive. I poked at it a bit with a toothpick thru both holes and can find no evidence of a fabric or other type of 'connective' matrix that could be considered a a die-cut or stamped 'pad' but rather just a semi-solid paste or putty-like substance that migrates an oily film under heat sway from the holes in top of pan. Also curious your base is plastic as my 200 base is definitely cast aluminum alloy as visible from the 4 outer screw mounting pad mating points between upper/lower halves which have had the powder coating ground off flat for ground continuity between upper/lower halves between the 4 outer mounting screws. There's also that shiney spot I mentioned above on the underside of the bottom cover where a wire was attached during powder coating. If yours is plastic I'm curious when that change occurred. Are you positive about that? Plastic would be a GIANT leap backwards temp & RFI/EMI leakage-wise... especially with the D-board sitting directly on it. My cellphone would ring constantly if within 1-1.5 meters of a plastic cover... BTDT!
