You probably should ask Kenwood first; or get the Service manuals and compare part numbers.
    Kenwood Tech Service is usually very good (24-49 hours) at replying to e-mails, but hurry before they take time off before the holidays.

    you can get some of the manuals here:

    Good luck.

A look at the service manuals shows the PC boards to be almost identical. There was a change in the RF BPF filter circuit to add additional filtering in the SDX and change the pick-off point. It appears (not guaranteed) that the SDX board would sub and work fine. Do you have either service manual?
