Hi Doctor,

The trade off is that the large supply pertebations from the output stage are directly coupled to the input stage's B+. The input tube, in a zero NFB amp, will pass on it's B+ pertebations as a signal to the output stage tube's grid.

While Low Z is NICE, in this case, what you propose will be offset to a greater degree IMHO by the pertebated B+ to the ultra critical input stage. If you lose music's information in the first stage, it cannot get passed on to the finals, your speakers, and your ears.

Off topic Doctor, call your stockbroker in South Korea sell ALL your stocks and mutual funds, ALL long term holdings you and your kids have, sell it all "at the market" and go into cash or cash equivalents, TODAY. This stock market has put in a bearish complex TOP ( 2000 - 2007 ) that we will never see again for many decades, and probably not in my lifetime !! If you want to play with stocks now, buy puts !! The best minds I know in market-timing have very heavily sold the market short....
