I have a B&W 852 switched inductor. I have seen it used with the 4CX1000A
but wondered if it might be OK for a GU84 or a pair of 4CX800As. Any
comments would be appreciated. Thanks,

Do the math-backwards.... Check the L, then figure what plate Z needs that 
value.
The 852's are for low ratio Plate Volts/Current as 4X1000's.
Never looked at an 852, but the 850's don't follow with the same plate Z per 
band.
One of Bill Orr's books talks about it and says move the taps.
