[Milsurplus] Harris RF-110/112 combo: Single-phase possible?

[Bruce Lane]

Fellow techies,

	The recent thread about the three-phase high-current switching supply, and some tricks to use it on single-phase, got me thinking about a Harris RF-110A kilowatt linear amp I have, along with its RF-112A three-phase power supply.

	Specifically (and I'm going to probably need someone who knows this hardware to answer this): Is there any way at all I could run the RF-112A off of 220V single-phase (well, two-phase if you want to get technical about it -- two hots plus a neutral)? I've looked at the schematic for the 112, and found that the main power transformer primaries are a bit of a complexity nightmare. I'm not well-versed enough in polyphase circuits to recognize more than some of it.

	Failing any sort of tweaks or mods to the 112, I would have to find an RF-124 power supply, which was designed to run the amp off single-phase to begin with. More specifically, I'd have to find it within local-pickup distance (west coast from WA State to the Bay Area), considering that there's no way I could handle shipping on something that heavy.

	So: Any mods? Or does someone have an RF-124 power supply they don't need, and that's within striking distance for me?

	Thanks much.
