You make a good point, Ed. I agree that a proper Q is appropriate,
and should be done. Actually, I would like to see more use of
bandpass filters on amps, but the cost and size of the high power
components make it unrealistic for most amps. I've looked at my amp's
output and the IMD products are far below the requirements. The third
harmonic is higher than I would like, but after filtering, it is far
enuff down to be acceptable. So - it can be done, with some care!
