Exactly. On 144 the weak signals are so weak that TX cleanness as well as RX dynamic range become a very difficult problems. You want a minimum number of TX stages to mess up the signal, and minimum phase noise. Most solid state amp's that might be available in the shack may not be clean enough to drive the big one. Hmmm.... years ago I was looking at a 144 legal limit amp project described in the 1988 ARRL Handbook. It uses a tetrode and produces full output with just 10W in. That one is now back on my list of dreams....
