These are the interior pictures of my 2 tuners.
The pictures above and one's posted before, are Truly what is needed for transmitting type tuners using Balance Line.
Those receiver-type caps can be used, but your talking power ratings of 10-50 watts PEP output.
To use a tuner correctly if using 100 watts carrier, IMHO minimum size tuner rating is 600 watts.
That DX100 needs a tuner rated at a KW by today's standard rating.
EF Johnson made a tuner for that called a Johnson Matchbox...It's rated at 275 watts
Continous Carrier I used one on SSB and ran a KW through it.
With antenna tuners... it's go BIG or stand-by for
smoke, fire and radio damage!!!
