Oh yes, for AM 60 watts would be excessive, based on my experience. The
Centurion has about 10 dB gain (+ a bit depending on band). Thus 60 watts in
would produce 600 out. At 600 watts, AM carrier modulated 100% is 2400 watts
PEP or twice the rating and capacity of the amp. Normally about 20 to 25 watts
drive is all that's needed.
