I'm really spoiled by my SB-220 -- I can use my 80m antennas that are
cut for the CW end all the way up to 3.9 MHz at least (with indicated
SWR over 3:1) just by tuning for maximum out. Same on 40. I understand
that few if any modern amps have this wide a tuning range, unless they
incorporate an auto antenna tuner as I think the Acom 2000A does.
Are there any exceptions? For example, will any of the Ameritron tube
amps handle this situation?
