I can't be more specific, as I have not seen a schematic of your set.
Your photographs indicate a signal overload somewhere.
You most probably have a gassy IF tube. Next probabilities are flaky AGC tube or gassy tuner tube. The high value resistors in the AGC circuit and the resistors in the tube that supplies the keying for your AGC are suspect.
