[R-390] Tube testing.

[Joel Richey]

You cannot test a 6LQ6 in an tube test and get any meaningful results, the tube tester cannot simulate the working conditions of that tube and it cannot test an 811, 572B, 3-500 or any any other tramsimitting tube, Sweep tube have been aeround for a long time , most of the time they loaf  but when you shout int the mike the draw a big hung of current , do you think your tube tester can simulate that, "NO".  Heres my idea, take your tube tester out to your trash can and desposit it. Just mu opinion, if you lke to see the needle move, keep using it.
