E57 power supply choke question

Hi,
My Electrola E57 went silent the other day while listening to the radio. I've tracked it down to a choke in the power supply which has opened up, possibly because the resistor in front of it has wandered down from its nominal 70K to 50K. Anyway, I've attached a partial schematic. Sorry about the image quality, its from a pdf that was scanned at a relatively low resolution.

The caps were all replaced about 6 months ago. Could someone give me a guess as to what inductance I should replace the open choke with? I suppose I could up the size of the caps and replace it with an appropriate resistance, but I would rather keep things as original as I can.

Thanks for the help,
Paul
