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.
Best regards from Theo PA3ERL
