[Collins] Cap answers.

[Dr.Gerald Johnson]

If you don't replace the black beauties, and come here whimpering 
about poor agc, audio distortion, low sensitivity, and an overly hot 6BF6 
expect to be told to replace all the black beauties. Leaky black 
beauties cause all those symptoms. The percentage leaky is at least 
95%. Its far more productive to replace them than to find them by 
troubleshooting, or to remove them for proper leakage testing. THEY 
LEAK. Orange drops are very much better.
