Take another look at the first paragraph of my post. I have no idea what the DSL401 has in its output stage, but to cause a 1.375 Volt drop across a 1 Ohm resistor, 1.375 AMPS are flowing. Even at the heavy Plate Dissipation my 7027A's endure at 35 ma, it would take 40 of 'em to draw that much current! :eek:

(Edit:)...and [i]furthermore... The service bulletin says that there is one 1 Ohm resistor [u]for each side[/u] of the push-pull output stage. So [i]each side[/u] would be drawing 90 ma in your example, or 45 ma through each tube!
