axplayer, be sure to tell your tech to set the AM deadkey at 2 watts so that you can use that amp with it.
SSB PEP should be set to about 20 watts max, but these radios usually do about that when peaked anyway so that should not be a problem.
just out of curiosity, what was your SWR when you were using the cheap center load antenna?
dont forget that when you run an amp, there are two different SWRs to worry about.
the one going into the amp (you can use the radio's internal meter to check this) and the SWR between the amp and antenna.
you will need an external meter between amp and antenna to measure this.
