Haven't check the amplitude of the oscillator on a 71.
I did on an early 16B, Two of the SW bands would die about a mc the low end of the band. Drove me nutz for a while only to find it was a missing resistor in the circuit. I didn't use a very sophisticated system just a modern ham transceiver with a S meter to track the oscillator.
In your case it could very well be a lack of feedback.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
