The Hallicrafters S108. It's alive

I just finished aligning the S-108 that had the bad IF transformers.  I
ended up having to fix 2 IF cans, realign the IF, replace the RF gain pot
and a 470ohm IF amp cathode resistor, and adjust the oscillator coils &
trimmers.

Can anyone give me an idea as to how "high" the image rejection should be at
30MHz with a radio with a single RF stage and a 455KHz IF?

This radio has about 20dB.
