I verified the band switch is connecting both sections on the condenser, and connections are secure; also no visible misalignment of the blades. I went through the entire tuner chassis and matched to the schematic; if I made an error, I am sure not seeing it. There was a resistor that was 30% out of spec and I replaced it. I tried swapping 6A8 mixer and oscillator tubes(with each other) and realigned the receiver; no change at all.
Can’t tell for sure on the other bands, but they seem off the same way at the higher end of the scale.
It doesn’t seem adding a small value capacitor in parallel with the oscillator section would work well, as the low end is accurate.
Ideas???

The cutout is for the speaker. Here's a photo from a different set.
