Since posting, I re-checked all the fuse clips. It seems that F1 and F2 on the power supply board are really loose and about to totally snap off. They are not gripping the fuses tightly. Looks like this will be the next fix on Rocky & Bullwinkle...the saga continues.
This is actually fairly common and some of the guys will replace fuse clips as a matter of course when getting a new pinball machine.
