Well, decided to add this one just for the case someone shorts out the secondary or something, now wondering of what concept to choose. So far got three alternatives - instant cut-off (keeping in mind it's not about DR coils, cutting off like 60 amps once will not destroy your switches), zero-signal cut-off (would be good for different conditions like excessive output capacitance, also will work well because the antenna startup is set onto 150kHz squarewave, so the edge will happen for sure ;) ) or immediate bridge shortout with an additional switch (would cost you a fuse ;) ) - so, what do you thing is better and more soft for the switches?
