Deric, that's nothing compared to what I have been mumbling..

I've looked at the AT5K, and see the ceramic body inductor. That is what I 
want, or an inductor with alot of taps and a big switch.

I've heard of the wheel on old ceramic body inductors occasionally jumping 
the track if the thing gets dirty, but otherwise, I've seen these kind of 
inductors 40 and 50 years old and still working properly once cleaned and 

For now, after I return this contraption, I'll use an old tuner I built in 
the 80's, which will handle a 100W rig easily, and be done with it. It does 
not have a balun, but maybe I can make one, apparently, by winding enough 
turns of RG-58 around a suitable form such as a 5" PVC pipe (as suggested 
in a book/website or two)

I will not condider an AT4K because the inductor (current production model) 
looks like the same or similar design apparently as the MFJ, er.. Ameritron 
ATR-30, and there are negative comments about the inductor if the 4K.

I have done some research on tuners, and my initial impression about the 
AT5K is this:

The price is high, but might be OK if it's as good as it looks, and the 
customer service rules etc seem a bit less friendly at first look. I'm not 
sure it's worth the money really. That is, a unit with a better switch and 
inductor should be $500, not $1000.

So I'm not really sure what to do. Maybe I just need to start looking for 
the appropriate parts. It's not rocket science, and then I can have a real 
chassis and thick front panel, etc. If I need fancy metering, nothing would 
stop me from making use of an old Drake 2KW unit I have sitting right here.

I don't care if it is big, that's what racks are for.
