If the meter needle (at Ic position of the switch) moves shaky, then 
most probably driver or final stage is auto-oscillating while the 
tune-up procedure.

Yes, you must do a complete re-alignment as per manual instructions, 
this happens because there's one shared rx-tx stage but the other two 
are not. So, because of lack of tracking, for rx you have a different 
setting of preselector than for tx. And is most notable at higher 
frequency bands.
I suggest you  first verify the oscillation issue checking both 
neutralizations and then perform the realignment.
Also, check the coupling capacitor between driver plate and final grid 
tubes; it becomes lossy after some time.

Goooooood luck  :)
