RE: VR tube as bleeder in choke input supply?

It also generates noise. The snubber in parallel is necessary and the 0.1 μF. max. mentioned previously can, sometimes, put you into relaxation oscillator territory. :>((
Just put 1 Kohm of resistance (appropriate power handling capability) per H. of I/P choke inductance in parallel with the 1st capacitor. Remember, the approx. critical current (in mA.) is given by V/L. Larger inductance = smaller critical current.
