Just wondering,  is 1500 Watts the most powerful amp you can buy new in the US?  I know you can buy used ones (i.e, SB-220, etc.) that put out more.
I see ads that say “Export Only” on some amps.  Is that because they can do more than 1500 watts or because the FCC hasn’t blessed them?
I’m just wondering for my own enlightenment.   Grin

I've seen photos of some things that look as large as a refrigerator,  I assume in the day those put out more than 1500 watts.

thanks.

You can buy anything in the US , however using it , different story.

Here is a 10KW, seen one on eBay last year that sold to a guy in Kansas however there are several "outlets" in the US you can get one. Here is a link.

The QRO 3K is about the most powerful amp produced in the US under current production. Alphas, ACOM and Ameritron’s are about 2000 to 2500 watts. Sometimes you can find a used Henry 3K or 8K for sale.

There are several hams (Bruce out in Tehachapi) who will build you an amplifier using a 4CX10,000 but you will need three phase run to the shack and a lot of money.

As many have said before a good antenna should be your first investment.

thanks, not really wanting anything like that. I was just wondering what was out there.  Sort of like a formula one race car.  Interesting to see and know about, but don't want to finance it, and its not street legal.  Grin

WALTERB:  1500w is the maximum legal limit for the U.S.  The SB-220 is considered  by many as a legal limit amp but it's doubtful that it will produce the full 1500w output.  Close but no brass ring.

The irony is that from 1500 to 3000 watts sounds like a lot but it is only 3db and barely noticable.

You start getting to the point where you need very good cable and connectors, and can have problems with the antenna. Even more so if you live high up in Colorado.

YUP things get serious when you get around 3kw out. Especially on the lower bands.

hi, when I said 220 I was talking about house wiring, not the model. maybe that's what he meant when he said 220?

600 to 800 watts sounds like plenty for me.   Grin

Yaesu FL-7000 is the best of the best for an Solid State amplifier , 600-700 watts all day long, WAY better looking than any other and built like a tank.

Sorry for the misunderstanding.
