>> The 2SC5739 does seem to have higher gain at higher frequencies than >> the 2SC2166, so your 20 meter output may improve if you change it, >> but I can offer no guarantees on that The plastic tab safety factor was obvious but, of course, I was wondering if there was an improvement in the upper frequency efficiency..... >>Should you make the change and find your power output is above 4 watts, >> reduce the setting of R1 to the 4 watt level. The components in the KX1 PA >> output stage can be stressed at power levels much in excess of 4 watts.
