Postby rcw » Thu Jan 09, 2014 11:54 pm

what is the most common problem and fix as one of the 572b's plates are get pretty bright red after a very short key down, the other tube reminds fine, almost no color at all? Thanks for any help. w7nwc

Would suggest the dull tube is in effect dead and the red one is overdriven. Could be various reasons - apply process of elimination. Taking safety fully and properly into account swap the tubes over and see if the observation moves if yes its the dull tube if not its the 'rig'.
