Took the first step towards returning this radio to its' glory... ordered a service package from Chuck!  The knobs are all there, dirty, but still usable.  The escutcheon, and push buttons, as you eluded Tom, are toast.  Hard to tell from what's left on the radio.  Did this set use brown or wine colored push buttons?  Speaker is full of dust bunnies, but no tears in it.  The lead wires to it look pretty feeble, though.  The rubber mounting blocks on the chassis corners are past their prime as well.  Time to start making a restoration parts list!  Take care, Gary

 Since it's a 1941 model then it would have brown plastic pushbuttons, the 1940 sets had clear wine coloured ones, but those also have a metal escutcheon. But don't get the 41-280 mixed up with the 42-380, whilst both had brown plastic pushbuttons and an escutcheon, they are not interchangeable, the 1941 models had 8 pushbuttons, the 1942 models had 9.
 One common problem that most of the 1939-42 Philco models have are bad power output transformers, so either go to AES and order a generic P-P output transformer, or go to Edcor and order one for P-P 41s or 6K6s, go by plate impedence in Ohms in teh tube manual. If you are really cheap you might be able to find a replacement in a junker radio-phono combo unit or chassis that uses either 6K6s or 6AQ5s as they both have the same plate impedance as a #41 tube.
