6AU6 - 6CL6 - 6146A trio is a very and associated circuitry produces some of the lowest distortion products when run at the right conditions (voltages, etc). Note at 75 watts the 6146 is in its sweet spot.

According to Rob Sherwood, the Collins 32S-3 produces the cleanest SSB signal on the air of any commercial amateur radio transmitters. 73, Charlie k3ICH -----Original Message----- From: elecraft-boun...@mailman.qth.net <elecraft-boun...@mailman.qth.net> On Behalf Of David Gilbert Sent: Sunday, September 13, 2020 9:51 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Why predistortion ?

As several people have pointed out, because of the 12 volt finals the transmit IMD performance of the existing K-line is relatively poor.
