Recently, the input SWR of my SB-220 has gone to about 3:1 on 10 CW. I can still drive it close to full output, but it ain't right. Without much instrumentation or the smarts to go with it, I'm wondering if there is something I can do more or less blindly. Does this likely indicate a failure in one of the three capacitors in the input circuit? Would it make sense just to get replacements and put them in?
