My SB220 has started giving me just a little less than half of the =
output I normally get on 10M.  Output on 20M and 15M seem to be =
unaffected.  I normally get 600W output and only run the amplifier in =
the CW/Tune mode.  Twice I heard a popping sound on the left side of the =
amp which I took to be the variable arching which it has not done for a =
while.  I have used it successfully for two years with all of R. =
Measures mods installed.  I have a brand new IC746 that the problem =
started with, but it does the same thing with my old IC735.  Could I get =
some suggestions on where to start looking for the problem?  Thank you. =
