[Amps] SWR increase on SB-220 input - my face is red

[Carl]

I believe Ive mentioned many times that operating WARC is best done in the 
CW position with that amp and around 750-800W. The fan should also be kept 
clean as well as the motor cleaned and lubed.

Clean any blackening off the socket connections.
