All the tubes appear to be the originals and test very good

There does appear to be one old repair. The 0.1uF in series with a coil that connects the chassis to B- appears to have been replaced with a 0.2uF Philco branded cap.
You can see it in the background here. The big bakelite looking cap in the foreground is right across the AC line. I clipped it out and will replace with a cap rated for across the AC line operation (X series).

I also clipped out the three section electrolytic cap and tacked in temporary replacements and powered it up.
B+ came right up and it actually works! One of the presets is set close to WGN and I was able to hear it clearly. Now it's not perfect, but not bad for old, leaky caps. Now I'll go ahead and replace all the paper caps and mount the new electrolytics more c=securely and safely. The line cord needs to be replaced too.
