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.
