Through the years I recall hearing of a couple other manufacturers who ran tubes (and other pahts) very hard, some to the extent that it became uncomfortable to work the controls on the piece, due to heat.A funny thing; when you look at the book for small signal tubes, the specs are always quoted at max plate watts and near max current. Maybe some manufacturers just believe the book. :^)
I have found that there is a certain amount of current required to get any small signal tube (that I have tried) 'on the cam', and that this current is, in every case so far, nowhere near max. The 5965, f'rinstance, is rated for 16mA, but after about 3mA the sound doesn't change (up to about 5mA, where I stopped testing). I run them at about 3.2mA just to make sure. Okay, I'm not getting the wonderful technical specs that I would if I ran them at 200V and 10mA, but the band don't care.
Oddness,
Poinz
