I took delivery of my KPA500 a few weeks ago and I am pleased with it. However 
I was some what disappointed that the manual did not come with a schematic 
diagram of
the amplifier. This has got to be my first piece of ham radio equipment that I 
have owned
in half a century that did not come with a diagram. 


The lack of a schematic now leads to this question. Just what is it that the 
front panel ON
switch is turning on and off ? The rear panel power entry module switch does 
kill all
power to the amplifier, but the front panel switch when Off, leaves some 
circuit power up. 

Anyone know what is left power on when the front panel switch is OFF and the 
rear 

panel switch is On ? 


Having the main On Off power switch on the rear panel is a bit of a 
inconvenience in my shack.Also having just only one RF output connector is 
problematic. Guess that is what the KAT500
with it's 3 Output connectors is for....
