Radios of this vintage that have not been serviced recently will always need the electrolytic and paper/wax capacitors replaced. Humming is good in that it indicates your speaker is probably good. If you read through some of the restoration stories on this site you will get a feel for what it would take to get your radio playing. A nice introduction is offered on Phil's Old Radio site. Now that you've gotten hum, I would not power it up any more until you do the recapping. While under the chassis you should also check the resistors as many often drift off spec and will need replacing.
Unfortunately the 1941 radios fall into the rubber coated wire era and many of the wires need to be serviced. You can read about that in Ron's Technical section on this Phorum.
If you decide to tackle the restoration, take lots...repeat...lots of photos as you go. You never know which photo you will need to reattach something that your forgot where it belongs, especially if this is your first time.
