Yes. Check out the Repeater-Builder web page for instructions on how to tune the stages in front of it for best efficiency. I retuned one I will be putting in service soon per that page. With a test element at 444.525, I have 2.2 W from the low-level amp output (BNC on the front), and it loafs at 70W. If I crank the output adjust pot up all the way, it does 112W! (DON'T run it that way tho-it WILL burn up!) Jim WD8CHL
