Dan,
"Running the tubes low" might also be referring to the practice of running them with a lower plate voltage at higher current, putting them into "Deep Class A" - the idea being that keeping the quiescant operating point more (than not) to the upper left of the curve chart (ie. lower volts at a higher current) will keep the tube from going into low current at the high end of the voltage swing where the curves start to lie down - meaning non-linear operation.If you do searches on "Deep Class A" you'll turn up lots of stuff. Paul Joppa's work on tube operating points is also very good to read. The link is to one of Paul's posts that I thought particularly interesting because of his remarks at the bottom about Deep Class A operation and its implications with respect to the output transformer,
'hope this is useful
