My amp is close to 7 years old and 20 has always required more drive.  27 to 30 watts on all bands except 20 where I'll run it up to 35 in a pinch. Elecraft suggested I send it in, but I haven't let the smoke out, yet.  Unlike your issue, I see a change when I increase drive. I drive the amp

My antenna is a TA-33-M-WARC. It's flat around 14.150, but goes up fast as you head toward .350. I have an FT-950 and FTDX-3000, and both need increased drive to get me to 500 watts. More concerned about the fault at 1.4:1. Although the two could be related. Anyway, the auto tuner handles
