"If someone has an amp that has high input vswr, why not break the path
between the amp relay and the input to the tube and insert a 200 watt
auto tuner? Between the relay and tube ... not in the receive path.
On the surface, this sounds like a relatively inexpensive way to
retain an otherwise good performing amp. What did I miss ?"
Several homebrew amp builders have done just that. One that comes to mind
is the 3CX1500D7 amp made by K8RA (SK). He installed an LDG auto tuner
after the RF input relay. You can see the tuner board mounted inside the
bottom corner of his amp. Scroll down to page 7.
