Thanks Martin. Mission accomplished. I was actually able to release the tabs from the front and I could pull them out a small distance. There was a lip though that prevented the knobs from coming through the front of the fascia.
Everything looks tons better except that whatever damage had occurred seemed to have moved the know toward the edge of the opening to the point that it rubs when I turn the knob. When I get to the point where I can read and write the serial EEPROM, I'll swap PCBs.
Thanks again,
George
