Only thing that comes to mind that it may be the transistor in the back of the radio near the power connector. You can use a TIP42 in place of it. Unsure if that only deals in AM and not the SSB side of things. Even if it doesn't fix it, it is a good idea to replace it from what was there originally.

I did this on a hunch with a simular radio.
Find test point 2 and measure voltage to board ground/ not chassis ground, on channels 1 and 40. Remember the number on 40, while keying slowly turn L13 to its max top and bottom while watching your watt meter for movement. record max and min voltages, or the voltage that lit up the watt meter. sometimes the specified 4.5 0n 40 isnt enough...
