Sometimes it's easy to 'overthink' these things. Huge chokes cost money and take up a lot of room whereas a couple of regulators are peanuts in comparison for this sort of job anyway.
I've been using my headphone amp for about 5 years with no problems. The heater regulator runs cool (admittedly using the metal chassis as a heatsink) and is built on a small piece of Veroboard. There is no measurable hum.
