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

It went very easily unt
It doesn't have to work as a filter either! It just needs to give some

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 ide
