For what it's worth.. I have four Elgar line conditioners. Two that work perfectly, and two for parts units. They are the 6000B series. I didn't pay more than $35 for any of the units. The will input 105-125vac and output 110-120vac (user adjustable) with better than .025% regulation, line or load, with less than .1% distortion. They will react to incoming transients, and fix it, within 20 microseconds! You can supply it absolute garbage, and it will output a pure, regulated sine wave, at up to 10 amps continuous. All my boatanchors see a steady110vac regardless of the line fluctuations. I have also seen as much as 130vac here. I'm convinced the power companies are doing this deliberately to generate more revenue. After using these conditioners (since the mid 70's) I wouldn't even consider plugging my precious old rigs directly into the line, unprotected. You wouldn't believe how stable the vfo looks on a DX-100 when the line voltage doesn't vary more than 30mv!!
(The published input range is 95-115, 105-125, or 115-135 user selectable, but they will actually handle 95-135vac on the middle setting if you're less than the 10amps max load) 73, Ed AA8TV Lakewood, Ohio
