Steve,
Don't be surprised if you see large swings in plate voltage. A "pole pig" is
not designed to be run backwards. It wants secondary current to be low and
primary current be very high. I ran one as a kid in California because
that's all I could afford. It worked but I only used it on CW.

Usually the transformer is the difficult part. You can simply purchase some
tube, so build the easy part around the difficult part.
Buy that big tube. ;)
