What what peak output do you think I should see from my 1500W amplifier?

Depends, what make is it? Is it solid state or valve? Output power will depend on what you put into it and without knowing the specs and put a good power meter that will read 2K between it and your antenna I couldn't make a guess.

I liked my Skipper 300 and recommend one highly. 600w pep when working tip-top, and due to the 1 driving 3 design, tends to provide the equivalent of RF speech processing on SSB for that extra punch!
- though they usually could use fresh tubes (8950, 6KD6*) and/or fresh high voltage supply doubler caps to get it up to spec.
It's also nice that it only requires about 12w-20w pep to fully drive it.
I would still have mine if it weren't for a local (dummy) CBer who wanted to swap for one, so I did and took home his Drake L4B, repaired the forty-cent HV lockout protection resistor he blew when he powered it up with the case open, and voilá, had a smart 1200w pep.
*Running 6v filament 6KD6 tubes require you series every 2 tube socket filaments, since the stock 8950 sweep tubes utilize a 12v filament.
