Roger,
That's why I'm looking only at non-roller/rotary inductor
tuners - to remove the mechanical movement variable and the concern
about an under-rated device in an affordable tuner.
Don't both the Dentron MT-2000 and MT-3000 tuners use only
tapped coils?

If the antenna in highly reactive (inductive) and the SWR is high the
voltage goes high. Neither the MFJs or Dentrons had a high enough
voltage rating for much over what I'd get when the 160 antenna was
resonant near the DX window and I'd go to the top of the band.
Moving the resonant point to the middle, or upper end of the band
would eliminate the arcing at 1 KW, but then I had concerns about the
small wire on the rotary inductor when operating at the bottom end of
the band.
They really needed a higher voltage rating on a larger cap and a
larger size wire on the rotary inductor for current on low
impedances.
