If you want to run SSB, not very many.

I had a local purchase one, and he had 2 amps... A 4 pill battlebox and my sweet sixteen. The VHP was WAY too much radio for BOTH amps. After it blew up 3 times, I spoke with Monika and their tech at Galaxy at length.

The basic premise was, that radio HAS to do pretty much the factory power output. It can go up and down, but at the sake of the reliability of the FETs. They flatly told me that if we adjusted the carrier power again, they wouldn't honor the warantee. To their credit, they did offer to swap the gentleman with another radio that was more suited to his needs... We said nah, and he gave the radio to his dad who is now happily operating it during the solar cycle mobile on 10 meters.

All that being said, you need a 16 pill. If you're going to go with 2879s, in class AB config, they will saturate with 15 or less watts in (in a proper circuit). Do the math :/

Hope that helps. If you're looking for base use, you can get a pair of 3-500Z's and overdrive them

[QUOTE="Toll_Free, post: 250168, member: 1736"] If you want to run SSB, not very many. I had a local purchase one, and he had 2 amps... A 4 pill battlebox and my sweet sixteen.
