I tend to agree with Rye and David. I'm not at all familiar with the Decca gear, but a varistor directly across a transistor is a protection technique I've seen used elsewhere in RF amplifiers. Its i

<< I am worried about drift but also thinking that they may be stable enough if kept in the 1 - 2MHz region. As well, they should (if identical) drift by the same amount and thus be self-correcting?
I found a good corona warning was given by a VHF broadcast radio left on while operating on LF - if coronoa appears, lots of loud crackles and pops are heard. >> Ah! So there is some practical use f

Hi Rik, Looks to me as if the net result is simply going to be a small loop in series with a series-resonant circuit. If antenna dimensions are an appreciable fraction of a wavelength, lumped reactan
