The Later Mastr Pro GE series base stations used a slanted heat sink for 
the 12.6 and 10 V pass regulators.  The chassis formed the back, and 
there was a cover on the front making a conduit for forced air from the 
4 inch muffin fan.  Poor field mouse got into the slanted heat sink, 
lost his grip, and went head first into the muffin fan - - did not 
decapitate but did trap him there and stall the fan - found the 
mummified remains some time later - then there are stories of a micor 
repeater loosing the 10 v return in the exciter - due to mouse urine 
destroying the trace on the PCB and various stories of stench.  Best 
Memorial Day wishes to all,  73, Steve NU5D
