In Reply to: parallel cathode bias resistors: "ghosting" effect posted by deathtube 667 on March 31, 2012 at 10:37:43:
Hi!
Whenever you apply two physical things to the same point of force application, any differences between the two objects will show up in the forces that emanate from this combo.
If you are parallelling two resistors on your cathode, simply make each one completely identical to the other one. In practice, this means better than 1/10th percent matching. Of course the same brand and wattages is also required.
