Help With K2 SSB Audio

[Wolfgang, Larry, WR1B]

Hi All,
I am looking for some suggestions on troubleshooting an SSB audio problem with my K2 (Ser # 495). With about an hour to go before the end of the W1AW/1 CT operation, I was on 20 m SSB and received a report of very distorted audio. At first I blamed it on the fact that the calling station was well off my transmit frequency. When a second caller also mentioned bad audio. I asked him to tell me more. He thought it sounded like a bad mic or something, so I swapped out my Heil Gold Line mic for my Heil headset. No difference. Then I went to the Kenwood hand mic that I use for casual operating. Again, no difference. Since he also seemed to be a bit off my frequency, I tried tuning him in with RIT. I realized I could not tune him in for clear received audio, either. So clearly my K2 has developed a problem.
I imagine it is something in the KSB2 SSB adapter. Any suggestions as to what might go suddenly wrong with the adapter? Or other suggestions as to the source of the problem?
I need help fast! I have a Kenwood TS-690S on the desk now, and it is a horrible CW rig, since it has no CW filters included! I want my K2 back! Thanks for any suggestions.

73,

Larry Wolfgang, WR1B

Larry,

One thing to try is to tuck the ribbon cable and speaker cable to the
KPA100 up into the space between the top of the Control Board and the
KPA100.  Remove the right side panel to easily do that.  The object is
to route those wires as far away from the KSB2 board as possible.
