Yes, I have used the auto and manual restore/rejuv functions on a Predicta and it didn't blow out the filament. I suspect it's going a certain % higher than the filament voltage setting.
Not sure if a LM317 would work since although it's DC it's not filtered.

I'll investigate this further via an actual lash-up possibly this weekend. My initial hypothesis is that the LM317/350/338 will just act as a peak-clipper. I also forgot to consider that the duty cycle is going to be something around 33% instead of 100%, so that helps the TDP side of things. Hell, it might be entirely possible that just a diode and a regulator will let you run strings as low as 35v off mains. I'm also curious to see how it affects the initial warmup. It might actually take
longer than a thermistor, because the hard maximum is 595mA in the example I gave. I intend to find out for us all.
