[Elecraft] NOT the feedline

[donovanf at starpower.net]

The Amphenol 83-1SP connector that many of us use is rated at 1000 
volts RMS, That well exceeds the voltage that most amateur 1500 
watt amplifiers can safely produce without much more severe internal 
damage to the amplifier.

The vast majority of HF stations with big power amps use UHF connectors 
throughout, and are without such problems as long as quality connectors 
are properly installed. The only problems I've ever had with connectors 
were the result the connectors being junk quality, and it hasn't been 
voltage breakdown. Rather I've had them fall apart, and I've had the 
center conductor melt.
