    Carl that is 100% correct, if you saw in the video I put some over-lay text indicating that as well. Hard to have it all. I had to just get a tuner done up from scratch to achieve my goals, but everything is a compromise really to some extent.

    quality all the way to the bank , i have a mfj-986 early model , works great but just not as good , James millen quality, i often see the separate roller inductors at ham fest , for a great price .

    Excellent points, Carl. I'm curious about the performance of each tuner in: 1) handling poor SWR antennas; and 2) a simple wire antenna, not necessarily a "long" wire. Opening up the case and showing the capacitors and inductor and their ratings really doesn't tell me much.

    I had some additional questions on the application of the lubrication on the roller inductor so here is that video as well if interested, also posted on my youtube channel:

    If that Palstar tuner is good for 3500 watts why does it need a fan blowing on the roller inductor? Hasn't anyone else noticed this? That's a bad sign. In typical "ham" fashion underrated components are being stressed to the max so Hambone puts fan on it. Reality check: Hit that tuner with 3500 watts CW into a highly reactive load and watch the ensuing light show. And Tyler- are you still afraid to drive your Chevelle in the rain?

    I am only showing what is inside each, yes it is odd... That is why you have to make your own tuner, I have thousands in the custom one only because of the Bird section, custom meters and custom panels...
    I am doing IR camera tests on a few components with pre-recorded transmissions to see what they look like as well, fun stuff!
    On my 1969 SS well that was a beast!!! Thanks for the memory hihi...
