When I was compiling the book LF Today, I could not find a reliable published linear amplifier design. Several people have mentioned recently that they are using linear amps. What circuits do they us

G0MRF Linear Amp. Complete construction article on his site. Mike WE0H WD2XGI Yes, I was aware of that one, though ironically Dave's web site was down when I was writing the book! Is this what everyo
I used to use a variation of an early version of it on 73kHz. Wasn't very efficient on 137kHz while keeping good linearity for PSK31 and similar, so I built the 700W Switch Mode instead of trying to
I have a very (can I use very in reference to A?) Class A Hafler P3000 amp, plagurised from John TAG design, and permission to run 1.8Khz envelope J3E on 137Khz (now that will upset someone!) I can a
What circuits do they use? How do they ensure they are linear? What efficiency do they get?> My amp uses a darlington pair/PNP-NPN complementary arrangement - much like some early audio amplifiers. O
