Personally, I found the article, (The Nearly Perfect Amplifier) very
informative. I remember that a friend of mine completed an amp using a pair
of 813's. He originally used the standard "coil wrapped around the resistor"
style parasitic chokes. He was cited by local hams for distributing unwanted
spurs on 144Mhz, (and where else has never been found). After reading Rich's
article, he added the NiChr hairpin style parasitic chokes. This was all
that was changed. Guess what?? No more spurs! NO nothing, but 700 watts of
RF at the desired frequency. So there is something to be said for these
style chokes.
We tend to mock ,what we don't know.......
