[Elecraft] KPA500 Power Switches

[Keith O'Brien]

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....
