Welcome.
97B is a beautiful tombstone radio.
http://www.nostalgiaair.org/Resources/903/M0013903.htm
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
Mike

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
