[Amps] Working on my Darwin award

[n8de at thepoint.net]

The late Jim Ringland, W8JIN, had a great amplifier built into his  
wall next to the shack desk which had a door in the front which  
allowed the changing of 'plug-in' coils for the finals.  This door had  
two interlocks to cut off the HV to the finals and ground the plates  
of the tubes.
One day, he opened the door and reached in to change band coils and  
got ZAPPED by the HV ... throwing him across his desk to the far wall,  
upside down behind the desk.
It seems BOTH interlocks had failed SIMULTANEOUSLY!

RIP Jim ... and the ZAP was not the cause of his demise, though it  
took a while for the burns on his hands to heal.
