Welcome.

97B is a beautiful tombstone radio.

This is the sch and some guidance. Alignment, BOM etc.
If want a better quality sch, ask Chuck Schwark here or at Philcorepairbench.com.

Tubes work at high voltages do be careful.
Also, do not plug it in (whoever did it was wrong - bad idea) before you recap it.

Start with recap.
One good thing that came out of plugging it in is - you know power is working and the speaker too.

Replace all capacitors except mica type. Electrolytics, tubular and backelite tub types.

Then proceed.

Best
