Hi Jorge,
That device would not stand a strike... As per the US Weather service,
(https://www.weather.gov/safety/lightning-power), a typical lightening
bolt runs around 300,000,000 volts, at 30,000 amps. That device is
speced for 4000 volts...
For Elecraft to protect the amp against a lightening strike as you
described you had, they would need to add a LOT more hardware than that
to the price of an already expensive amp, and most people would never
see need the protection. Hence why they don't even try and protect
against a direct lightening strike.
The onus for lightening protection always rests with the device owner.
73, and thanks,

I am not an engineer and I don't know anything about electronics either,
but I am very receptive to the solutions that many radio friends give me.
which made me think if the kpa1500 or k4 usb was built with something
like this,

Jorge,
I would imagine if you approach Elecraft with that mindset, their
thoughts will be you should take care of your own lightening protection.
