[Elecraft] KPA500 Bypass Power Limit?

There was no question regarding if the amp had a bypass 'mode' It was as 
you quoted;

"How much power can I run through a KPA500 that is in BYPASS"

So in 'standby' mode the amp is 'in bypass' as its input is connected to its output.

So it seems an unnecessary invalid initial answer to a question that did not exist regarding bypass mode.

However ;

"You may run up to 200 watts through the KPA500 in STBY." was on the money.

Twenty-five watts from the driving transceiver will illuminate the first POWER LED. You may run up to 200 watts through the KPA500 in STBY."
