[Lowfer] Re: Amplifiers for 136k

Hi Jim,

Thanks for the excellent hints and kinks for 136ing!

Do you know of anyone who has actually measured and cataloged the amplitudes 
of the harmonics for a square-wave driven LF loop, particularly using 
step-down transformer coupling? This is something I could do fairly easily 
with my setup.
