[Elecraft] Internal Antenna Tuner and SPE Expert Amplifier Questions

[pastormg2 at verizon.net]

Good Morning,
It's Mark Griffin KB3Z. I was looking at an SPE Expert amplifier and I see it has an internal antenna tuner which can handle SWR's of up to 4:0. But, I was wondering if I connected the output of my K3 to the input of the amplifier and then the antenna to the output of the amplifier, If I used the K3 internal antenna tuner to decrease the SWR to a reasonable level would this work? I don't currently have the internal antenna tuner in the K3. It is perhaps a bad question to ask, but I am currently using a Palstar AT2K as my antenna tuner. Any help or advice would be greatly appreciated.  Mark Griffin, KB3Z
