[Amps] 3-500Z glitch resistor

[Carl]

The commercial ones are about 3-5" long and fit into a small size 
resistor clip. A vaporizing bare wire isnt exactly giving me a warm 
feeling. That reminds me of an old SF story.

My commercial CW/SSB ham amps are too compact for chancing that. Maybe 
for the rack mounted 250TH's and 304TL's AM amps (;
