Oh, I thought I took a photo of the power transformer, but it didn't
come out.  I'll try again.
And Bob says it'll work nicely into at least 2:1 SWR at full power,
maybe even higher, but they're not ready for "test to destruction"
yet.

   It's nice that you bring up the SPE 1K, since it demonstrates very nicely the loss you can suffer with a built-in tuner.  

   The ARRL review
   (http://www.arrl.org/files/file/protected/Group/Members/ProductReview/pdf/pr0909.pdf)
   said that there was 100-200W loss in the internal tuner, and
   presumably this is into a matched load in the laboratory.

   With a mismatched load the losses are generally going to be even higher.

   With solid-state power costing upwards of $3-$4/watt these days
   ($3.20 in this case), why anyone wants to leave $500-600 worth in
   the box is beyond me.  But then I could never get my arms around
   the whole mismatched antenna/ladderline/balun/tuner thing in the
   first place.
