Ceiling fan speed control caps work great. Gobs of 'em on Amazon.

Were the ballast tube burnt out and unobtainable sure I'd run an AC capacitor in it's stead and not think twice about altering the circuit , in my opinion running condition trumps original condition with most tube radios . But , since I'll bet replacements for the original ballast tube are still available , and since the ballast tube carries no built in safety hazard by design like the curtain burner cord does , I'd be inclined to leave the circuit as is and stock up on a couple or few spare ballast tubes while they are still somewhat available .
