The person starts with establishing that this is a Philco 610, then goes to, say, Riders (www.nostalgiaair.org) and downloads the schematic.

Then that same person removes the chassis ands replaces all paper capacitors (whether tubular or backelite blocks) and electrolytic capacitors.

Then (the same!) person checks the tubes.

Check the speaker, especially the field coil and the output transformer.

Then you could power it up, using a Variac, check the voltages, and, should it be OK, see if it actually works, receiving stations.

If it does not, the person goes to troubleshooting mode.
Check resistor values (actually doesn't hurt to do that after the recap), check the magnetics continuity.

Then ... well, you have to get to that "then" first.
