My recent experience with Palstar has not been good. An expensive DL1500
dummy load in which the SO239 had not been mounted correct bwith the
locknut still ten turns loose,
requiring dismantle and repair new out of the box by myself. Also a new
expensive AT2K tuner in which the roller inductor shaft had not been
graphite greased nor tensioned.
My SPE amp @ 400w went out on alarm quickly until I disassembled and
repaired myself. I found Palstar support rude and in self denial of the
issues I raised.
In hindsight I should have saved a heap of money and gone with MFJ.

Ten-Tec Tuner,
This might be it, Peter. ! I've used (and loved) the Ten Tec 229 and
238 tuners, but some of their fixed capacitors are under-rated for
power. This is fairly well known among Ten Tec users, so I read about
it somewhere and replaced those in my tuners with caps having higher
power ratings.
There's another design flaw -- their antenna selection switch fails to
to provide a return for RF current, using the chassis instead. This
adds inductance in series with the signal path, which increasingly
degrades SWR and crosstalk with increasing frequency. Palstar makes
the same mistake in tuners I saw at Dayton 8-10 years ago. When I
pointed it out to a guy in their booth who claimed to be its designer,
he told me I was crazy!
