Too little of the schematic for us to help.

On the other hand, why not pull the choke apart and see if it can be repaired? Even if not, you can see the wire size, weigh the unit, and get very close regarding its ratings.

Well, I've finally had a little free time again. Dug out my old copy of Millman & Halkias, made some assumptions, did some calculations, and decided that about 7 Henrys @ 50 ma would do the job. Found a Weber 9H choke @125 ma (replacement for a guitar amp) for pretty cheap and plopped it in. Replaced the out of spec resistor at the same time, and its all working a treat again.

Here's what it looks like (sorry for the lousy photo. used my phone since I was too lazy to go upstairs to get my camera)
