One-Electron PRC chokes as PS input choke?

Pete,

I don' know the answer to your question, but Jack at Electra-Print wound a choke for a choke input PS (~30H for a 60mA DC PS) for me for a bit less than those cost. I don't have the receipt in front of me, but I think it was about 2/3 the cost. I have been abusing it at 75mA (w/ a small 1uF input cap to raise voltage a tad) without issue, noise, or ripple.
