K. G. Macleish, W7TX, was listed as a Silent Key in the September 2008 issue as being in Chicago, Illinois. He actually lived in Tucson, Arizona.
In “Converting a Heathkit SB-220 Amplifier to 6 Meters” [Apr 2008, pp 38-40], the author reports that the specified 100 pF 4 kV air variable plate tuning capacitor has been found to have too high a minimum capacitance to be resonant in some units.
