[Elecraft] K2: BFO range problem on early S/N K2

Hi, We are working on an older K2 (S/N 152) to fix apply some simple mods and generally update things. After doing some straightforward mods (control board exclusively) we decided to touch up the filter/BFO alignment as the perceived bandpass seemed to be tuned a bit low. It went very easily

[Elecraft] mods to K2

I unask the first question (how to raise K2 output power). But in self-defense, I knew that: PAs have better distortion properties with higher supply voltages 14-20W is about 1 dB but 10-20W is 3.01 dB (3 dB MATTERS!) operating above 10W on ssb with the K2 was not a good idea
