** You're right, Todd. When I was a young whippersnapper, John
MacDonald, W6SDM, told me that for SSB, it takes c. 10db (1.67 S-units)
to make a clearly noticable improvement. Thus, if one runs a pair of
3-500Zs, and one wants to deliver a clearly better S/N ratio at the RX
end, one needs a tube with handles.
