On CW the GAIN control varies a DC bias on the Balanced Modulator diodes to "unbalance" them. Perhaps that section of the GAIN control has lost it's ground. That section isn't used for any other function.

I have a T-4XC that works fine on SSB but when I switch to CW and key the transmitter, It has full or a lot of drive applied and the gain control has no effect or control over the drive. Has anyone out there run into this before? I thought I would check before I start looking for the problem. Thanks, Terry W8NJR
