I own a MB-V Nye Viking Tuner (the one they sell now without the antenna
switch) and am pretty happy with it. I bought it at Dayton about 10-13
years ago. It's been back once to have the inductor cleaned up. N4CT has
one of the ones with the switch and is happy with his. He feeds all types
of wire antennas at 1500 watts out with no problems. I also have a Johnson
transmatch and have used a TenTec and smoked one MFJ.
I have run 1500 watts in SS SSB into full size 80 meter delta loops and 80
meter zepps for long periods on 40/80 with no problem. This was using the
common 450 ohm open wire feeders that are sold these days. I have run full
power into a 80 meter tilted delta loop on most bands between 10-80 with no
problem. By the way, we smoked a TENTEC 229 B tuner balun running 1500
watts into the loop on 80 in SS a few years ago. We had bought the tuner
used and suspect that the balun was not a TENTEC (I'm pretty happy with my
Omni V and Titan). I have not used the Nye Viking to feed coax fed antennas
on 10-80.
At my last house (where I had room for 160 antennas) I tried one antenna
that worked with the tuner and one that worked only with a tuner
modification. At that time I had a 55 foot tower with a TH7 on top and 40
and 80 meter quarter wave slopers. I was on a hill. I tried a 160 quarter
wave sloper (the bottom of the sloper was 3
0 feet below the house down the hill). The only way I could get the tuner
to work was to add some capaitance.
Later I put up a 3/8 wavelength inverted L with about 50 foot vertical
section fed against about 25 135 foot radials. I just ran some 450 ohm line
out to the base of the L and connected one side to the L and the other side
of the open wire line to the radials and to the tower ground. This antenna
worked fine at 1500 watts with the Nye Viking tuner. I have no idea if
this is an efficient way to feed an L compared to the more traditional
methods (comments here
please). I had no other antennas to compare to and it was CHEAP!

BTW, a while back I put out a question about STacking C3's and had a number
of requests for a summary of what I learned. Unfortunatly, those resonses
are on my Thinkpad which has been in the shop for about a month.
