Hi!
Those current swings due to the music signal will be mostly supplied by the last filter cap in your supply, so your input choke will not see them, at least only to a much lesser degree.
I'd recommend a bleeder resistor which ideally ensures critical current draw at all conditions even if the output tube fails and does not draw current. Depending on the voltage this might require to dissipate an unpleasantly high power in the bleeder. In that case make sure your caps have a voltage rating which is able to cover such falut conditions in which the voltage rises by up to 50%.
I'd rather get a choke which is speced for the applicatoin than getting one with much higher current and hoping it will not procude noise
Best regards
Thomas
