Hi Dave
Hopefully, this is a lesson learned. Not so much about the 80 psi, but about the steel wool.
It is best to never use steel wool around electronic circuitry. Steel wool fibers are conductive. They can go anywhere and everywhere. They can get in between plates of your tuning condenser. They can get into trimmer condensers, IF transformers, you name it.
I suspect if the 80 psi had broken a lead wire, you would have found it by now.
Since you have reception on the preset pushbuttons, then chances are your set's IF transformers are OK. I would be looking for stray fibers between the plates of the tuning condenser, as Doug K. mentioned, and the contacts of the three tuning band pushbuttons. Heavy use of contact cleaner in conjunction with careful use of a toothbrush on the contacts of the pushbutton assembly is something you may try.
