I'm one who often replies with a straight answer that is not appreciated for the effort intended. Think about this: If you can read the user manual and under stand what needs to be done to use it, it is the one for you unless there is some other circumstance to disqualify it from consideration. 1. You need a Tuner between it and the feed line for the wide band uses you stated unless you intend to have a resonant antenna set for each band. 2. A. Tube type needs to be adjusted per band, (Plate and Load adjusted) and Tuner adjusted to match. B. Solid State may be auto tune or wide band select but still need the Tuner to be set unless you also have an Auto tune Tuner. 3. The Tuner needs to be rated for the amplifier power level +. So you need two pieces of equipment right off. Refer back to the opening statement. Most of the equipment PDF are able to be looked at off the Mfger website. Not much different than shopping for Car or Refrigerator to meet your objective. Good luck.
