Thanks John, I think the company made a model 802 choke which was more
suitable for "generic" applications at 1.8 mhz.

I used one as a screen choke at 2800 KHz, in a 100 kW amplifier at work.

It was fine there, but not sure about 1900. This was 12 years ago. I 
took data on a B&W 800 using a vector impedance meter and plotted it. If

I can find it tomorrow, will scan and ship it here.
