I can give reviews of that kit since I built and tested it for Ian in my 6M
NCL-2000 as far back as pre production in the 90's and have built many more
for stock and 6M converted NCL-2000's, various Johnson's including the 6n2
T-Bolt and other tetrode amps.
IMD testing has shown a solid 3-5dB improvement with some a bit more and
that was without cherry picking the audio frequencies as does the ARRL.
It is easy to assemble, instructions are superb and it works as advertised.
I highly recommend it AND I have no financial interest in it.
