.... my recollection of the st70 being biased "correctly" (below 45ma), is that it looses a bit of dynamics. will try that tonight.
i biased my st70 down to about 1.35, and blah, didn't quite like it - slow and lacks dynamics, so it's back to 1.56 as recommended by the designers. luckily, the power transformers have been upgraded but they still get very hot...
yehey!!! 1.56V!!!!
