>Hello and thanks for reading this,

>I have big problems with my yeasu fl2100b Amplifier.
>I have a pair of new tubes in it because one ore two tubes are getting a
red
>color, when I tune with low power ( 5 watts input).
>The power output seems good only on the 80 meter band I can get a dip or
>full power with the tubes.
>Also with one tube (572B) the onetube installed for testing is colored red,
>With my old tubes I get the same problem as above.
>I have cleaned the bandswitch and the coaxrelais and all that is okay.
>The resitors on both tubes are also new so that must be no problem.
>
>Do you recognize this problem, please send me an e-mail.
