Dear Mal, LF Group, Something is wrong if you need to adjust the tuning within this range - the output should be flat within a fraction of a dB over the whole band without re-tuning. Nothing wrong,
Thought it felt a bit dubious, but I hadn't got the core loss information available so couldn't justify the feeling. Anyway, isn't 2 mix - the red coloured one - the wrong material for this frequency
Dear Andy, Mal, LF Group, Well, up to the point that it won't saturate - but that is just the first hurdle. I was slightly amazed to find the micrometals catalogue at work in my filing cabinet, conta
