      Another thought might be to buy cheap one of the old palomar "broadband" fm/ssb bricks cheap and buy a filter kit from hfprojects. I may just do that as I have an old palomar that my dad used to use (legally) on 10 meters. It worked very well on that band with an ft7 driving it.

If you want a similar amp that has some chance at being "legal", consider the RM Italy HLA 300. Of course it is a lot more expensive, due to it having 1) appropriate band pass filters, 2) auto band selection, etc. Most reviews have said that these amps will not produce the advertised power, and will produce too much distortion if pushed anywhere near the maximum they are capable of producing. But even the HLA versions of the amps are cheaper than equivalent amps from better producers. You get what you pay for, but many have been happy enough with these amps if they are used appropriately. You should definitely read some reviews so you understand what you are going to get for your money.
